Embodiment
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.
The present invention proposes a kind of simple and realize the low demand control system of cost, has intelligent electric meter novel, that can carry out demand response in this locality, and needn't carry out electricity usage control by the opertaing device of Utilities Electric Co. is long-range.
Fig. 2 is for having the structural representation of the intelligent electric meter of local demand response in the one embodiment of the invention.This intelligent electric meter comprises: first communication unit, CPU, signal acquisition process unit, user interface, digital output unit.
Wherein, first communication unit is used for receiving electric power message from the outside, offers said CPU.Generally speaking, the electric power message that first communication unit receives is sent by the opertaing device of Utilities Electric Co., is used for simply indicating the electricity consumption situation of whole electric system.
Said CPU is used for the configuration needs response policy, and searches said demand response strategy according to said electric power message, generates the corresponding control command restriction or the electricity usage of recovery load.
In one embodiment of the invention, the signal acquisition process unit is used to gather in order to confirm the electrical quantity of power demand.Correspondingly; Said CPU is further used for: the restriction thresholding and the recovery thresholding of said power demand and setting are in advance compared the power demand state that obtains; And search said demand response strategy according to said electric power message and power demand state, determine corresponding control command.When concrete the realization, power demand can be calculated by the signal acquisition process unit, and the signal acquisition process unit of this moment adopts DSP to realize.Certainly, simple simulating signal extraction and A/D conversion also can only be carried out in the signal acquisition process unit, and the electrical quantity that collects is offered CPU, calculate power demand by CPU.The concrete realization that it may be noted that the signal acquisition process unit can be repeated no more with reference to prior art here.
In another embodiment, CPU is further used for: detect the load electricity consumption situation of one or more load, search said demand response strategy according to said electric power message and said load electricity consumption situation, determine corresponding control command; Wherein, whether said load electricity consumption situation is used to indicate the electricity usage of said one or more load to be restricted.
In another embodiment of the present invention; CPU is further used for: the restriction thresholding and the recovery thresholding of said power demand and setting are in advance compared the power demand state that obtains; Detect the load electricity consumption situation of one or more load; Search said demand response strategy according to said electric power message, said load electricity consumption situation and said power demand state, determine corresponding control command; Wherein, whether said load electricity consumption situation is used to indicate the electricity usage of said one or more load to be restricted.
User interface not only shows electrical quantity, and shows the configuration of demand response strategy, makes the user to be provided with, to revise or to upgrade this demand response strategy.
The control command that the numeral output unit is used to send the CPU generation according to control command, limits or recovers the electricity usage of its one or more load that connects by said switchgear to switchgear.In Fig. 2, switchgear can be isolating switch (circuit breaker), converter (switch), relay (relay) etc., is arranged on subscriber's local, is used to control the electricity consumption of subscriber's local load.Particularly, digital output unit is through corresponding electric signal, the switching devices control that links.
In the system that the present invention proposes, the opertaing device of intelligent electric meter and Utilities Electric Co. is communicated by letter to obtain simple electric power message.Further, the electrical quantitys such as voltage and current of intelligent electric meter real time monitoring such as electric system are to confirm power demand.Certainly, intelligent electric meter can also obtain current load electricity consumption situation, knows promptly whether the electricity usage of one or more load is restricted.
In another embodiment; The control command that CPU generates also can offer switchgears such as isolating switch, converter, relay through second communication unit shown in Figure 3, so that the electricity usage of load is limited or control such as recovery.It may be noted that when adopting second communication unit switching devices to control, require switchgear can resolve the signal of communication that the second communication unit sends.
Can find out that the core of intelligent electric meter provided by the invention is that its internal configurations has the demand response strategy.In one embodiment of the invention, the demand response strategy has two inputs, an output, and is as shown in Figure 4.This demand response strategy can be disposed by the user.These two inputs are respectively: (1) electric power message; (2) power demand of systematic survey (power demand, the power demand of PD) perhaps predicting.Alternatively, when intelligent electric meter has the function of predicted power demand, can adopt demand response strategy more flexibly.One is output as: the digital output unit or the second communication unit that arrive intelligent electric meter according to the demand response strategy output control command of correspondence.
When concrete the realization, the demand response strategy can only have an electric power message input, and electric power message, load electricity consumption situation, these three inputs of power demand state also can be arranged.
Further, in one embodiment of the invention, pre-configured demand response strategy writes down, is stored in the intelligent electric meter with the form of demand response matrix.This demand response matrix has electric power message, load electricity consumption situation, these three dimensions of power demand state.
For this dimension of electric power message, in concrete realization of the present invention, the electric power message that the opertaing device of Utilities Electric Co. provides has 3 kinds of values:
(1) electric power message is logined (Utility message check-in), shows that whole electric system this moment reaches the electric power peak demand, and Utilities Electric Co. hopes that the user limits load in order to avoid risk appears in system.It may be noted that electric power message is logined can be regarded as restriction of message.
(2) electric power message is published (Utility message check-out), and the electric power peak demand that shows whole electric system is mistake, and Utilities Electric Co. notifies the user to return to normal running.Certainly, electric power message is published and can be regarded as recovering message.
(3) unregulated power message shows user behavior place one's entire reliance upon user's actual loading and self-demand, can not receive the influence of whole electric system.
For this dimension of load electricity consumption situation, can the influence that one or more load brings according to function or load response be divided into a N load group.Correspondingly, the value of load electricity consumption situation comprises and N+1 is respectively: electricity usage is unrestricted, 1 load group of restriction ..., N load group of restriction.
For example; Load is divided into HVAC (HVAC; Heating ventilation and air-condition), illumination, running time equipment, four load group of key equipment (seeing table 1) more flexibly, then the value of load electricity consumption situation can for: electricity usage unrestricted (or full load), restriction HVAC, restriction illumination, restriction operation time is equipment, restriction key equipment more flexibly.With the restriction illumination is example, and this value is illustrated in further restriction illumination on the basis of limiting HVAC, in table 1, is expressed as two white circles intuitively; The restriction operation time more flexibly this value of equipment then be illustrated on the basis of restriction HVAC, illumination equipment more flexibly of further restriction operation time, in table 1, be expressed as three white circles intuitively.
Consider the significance level of different loads group, can be with mainly alternative (significance level be 1, promptly inessential) of HVAC as load limitations, also can pay attention to (significance level is 2) of throwing light on.And then be running time equipment more flexibly; For key equipment, need still reward in punishment, and restriction is considered this two aspects compromises that influence that user's business causes.Least important load group can limit last recovery or release at first, and the load group of most critical will be discharged by last restriction at first.In concrete a realization of the present invention, can use storehouse memory load group, as shown in Figure 5, restriction and release just are analogous to earlier to go into afterwards pushing on and popping in (FILO) storehouse.If use the current load electricity consumption situation of pointer mark, under the condition of full load, pointer=0; Under the condition that idling carries, pointer=N (N is the load group number).
For this dimension of power demand state, what need to consider is that a typical commercial power bill is not only chargeed to energy (or kilowatt/hour, i.e. kWh), but also the contract of signing according to user and Utilities Electric Co. is to the peak demand charging.Arrive at power demand before the peak demand of contract engagement, will take load limitations.Just carry out load limitations if arrived the peak demand of contract engagement, often late.Therefore, in demand response strategy provided by the invention, two demand response thresholdings are set are used for confirming the power demand state, as shown in Figure 6.
It at first is restriction thresholding (Pshield).When the power demand of measuring or predict (PD) is higher than limiting door in limited time; Will take load limitations; Since the peak demand of arranging in the contract that next peak demand possibly surpass and Utilities Electric Co. (utility) signs, and this fine or the electric power supply that can cause Utilities Electric Co. usually stop.
Next is to recover thresholding (Prelease).When dropping to, recovers under the thresholding power demand, and former when pre-existing load limitations, then be said restricted load restoration electric power supply.
Correspondingly; The value of power demand state can be according to power demand and restriction thresholding that is provided with in advance and the relation of recovering thresholding be provided with, comprise following 3 kinds: power demand less than recover thresholding, power demand be in recover between thresholding and the restriction thresholding, power demand is greater than the restriction thresholding.It may be noted that the risk of being not only that above-mentioned two demand response thresholdings consider, also have the efficient of system's operation.
Further; Contract peak demand (Pcontracted) can be set; If the user charges to peak demand in contract, then agreement is provided with Pcontracted as agreed, otherwise can Pcontracted be set according to the full load demand (peak demand) of system.Therefore, in another concrete realization of the present invention, the value of power demand state has 4 kinds, comprising: PD less than Prelease, PD greater than Prelease and less than Pshield, PD greater than Pshield and less than Pcontracted, PD greater than Pcontracted.In addition, in concrete a realization, can be set to 95% of Pcontracted by Pshield, Prelease is set to 80% of Pcontracted.
Can find out; The different values of above-mentioned three dimensions are combined; Can obtain different demands situation (demand situation); When receiving that electric power message is logined, load electricity consumption situation is that electricity usage is unrestricted, and the power demand state is that power demand is exactly wherein a kind of conditions of demand greater than the restriction thresholding.When the load group number is N, if the power demand state has 3 kinds of values, total (N+1) * 3*3 kind conditions of demand; If the power demand state has 4 kinds of values, (N+1) * 4*3 kind conditions of demand are arranged then.Under every kind of conditions of demand, the user can have 3 kinds of dissimilar respondent behaviors (response action): (1) no respondent behavior; (2) the next load group in the load group storehouse (as shown in Figure 5) is limited (prerequisite is that still exist can confined load, and promptly pointer is less than K); (3) a nearest confined load in the load group storehouse (as shown in Figure 5) is discharged (prerequisite is to have confined load, and promptly pointer is greater than 1).In load group storehouse shown in Figure 5, significance level is that the load group of K places stack top, and significance level is that 1 load group places at the bottom of the stack.It may be noted that the behavior of every kind of conditions of demand corresponding response all is configurable.
Through above-mentioned configuration, the example of the demand response matrix that intelligent electric meter had is seen table 1, total 5*4*3=60 kind conditions of demand.This demand response matrix can be configured according to the different demands situation in practical application, is used for the electricity usage of the one or more load group of control (i.e. restriction or recovery).
Table 1 demand response matrix example
If the user does not consider to be configured to every kind of conditions of demand, also can adopt other forms of demand response matrix.For example, as a conservative option, can there be respondent behavior forever; Option as Utilities Electric Co.'s award tendency type when the electric power message that occurs being used to limit (being that electric power message is logined), always limits load; Option as system's operation tendency type makes the systematic electricity demand remain between Prelease shown in Figure 6 and these two thresholdings of Pshield through restriction or release load group.Certainly, can dispose the demand response matrix of self fully by the user.
Fig. 8 may further comprise the steps for carry out the method flow diagram of local demand response in the one embodiment of the invention at intelligent electric meter.
Step 801: through user interface configuration needs response policy on intelligent electric meter.
Step 802: the value of the electric power message of confirming to receive.
Step 803: the value of confirming load electricity consumption situation.Particularly, can be information such as confined load group number or which load group are limited.
Step 804: intelligent electric meter compares the power demand that calculates and Prelease and these two thresholdings of Pshield, thereby confirms the value of power demand state.It may be noted that intelligent electric meter can periodically calculate power demand, rather than when carrying out local demand response, calculate.
Step 805: the value according to above-mentioned three dimensions finds corresponding conditions of demand from the demand response strategy that is disposed, and determines pre-configured respondent behavior and generates control command in view of the above, and Fig. 7 is seen in the use signal of demand response strategy.
Step 806: intelligent electric meter sends to corresponding switch equipment with said control command through digital output unit; Be used for breaking off (turn off) or connect (turn on) said switchgear, thus restriction or the electricity usage that recovers the load group that this switchgear connects.
It may be noted that adopting the demand response strategy of matrix record is an embodiment in the local demand that has intelligent electric meter of the present invention is controlled, also can adopt other modes (such as expert system or artificial intelligence approach etc.) to realize the demand response strategy.
The intelligent electric meter that has the demand response strategy provided by the invention can be applied to industry, building automation, dwelling house application etc.Can find out that from the embodiment of above description intelligent electric meter provided by the invention has following one of them advantage at least:
(1) saves cost.The present invention provides local demand control, and does not adopt complicated long-range demand control system.It may be noted that long-range demand control system needs expensive equipment, complicated software, various communication facilities, telecommunication cable and general layout usually.
(2) be easy to realize.The user only need dispose the local intelligent ammeter, just can obtain required demand control result.Do not need complicated IT structure in the power consumption side.
