[0068] (3)无电力消息,表明用户行为完全依赖于用户的实际负载和自身需求,可以不受整个电力系统的影响。 [0068] (3) no power message, indicating that the user behavior is totally dependent on the actual load of users and their needs, it can not affect the overall power system.

[0069] 对于负载用电状况这一维度,可以将一个或者多个负载按照功能或者负载响应带来的影响划分为N个负载组。 [0069] For the electrical load status of this dimension can affect one or more functions in accordance with the load or the load in response to bring the load into N groups. 相应地,负载用电状况的取值包括N+1个,分别是:电力使用无限制、限制1个负载组.....限制N个负载组。 Accordingly, electricity load status values ​​include the N + 1, are: the use of unlimited power, a load limiting group of N ..... limit load groups.

[0070] 例如,将负载划分为暖通(HVAC,heating ventilation and air-condition)、照明、操作时间较灵活的设备、关键设备四个负载组(见表1),则负载用电状况的取值可以为:电力使用无限制(或满负载)、限制暖通、限制照明、限制操作时间较灵活的设备、限制关键设备。 [0070] For example, the load is divided into HVAC (HVAC, heating ventilation and air-condition), the lighting operation time of the device more flexible, the key four load equipment group (see Table 1), the load condition of the power take values ​​may be: using unlimited power (or full load), restriction HVAC, lighting limit, restrict the operation time of the device more flexible, the key limiting device. 以限制照明为例,该取值表明在限制暖通的基础上进一步限制照明,在表1中直观地表示为两个白圈;而限制操作时间较灵活的设备这一取值则表明在限制暖通、照明的基础上进一步限制操作时间较灵活的设备,在表1中直观地表示为三个白圈。 To limit the lighting, for example, the value indicates that further restrict the illumination to limit the HVAC based on Table 1 in two visually represented as a white circle; the time limiting operation of this apparatus more flexible limit value indicates that HVAC, further limiting the operating time of the device more flexible on the basis of the illumination in table 1 represents three visually white circle.

[0071] 考虑到不同负载组的重要程度,可以将暖通作为负载限制的主要备选(重要程度为1,即不重要),照明也可予以考虑(重要程度为2)。 [0071] Considering the importance of the different load groups, as may be the main HVAC load limit of the alternative (1 degree of importance, i.e. not important), the illumination may also be considered (as the degree of importance 2). 紧接着是操作时间较灵活的设备; 对于关键设备,需要在惩罚还是奖励,以及限制对用户的营业造成的影响这两个方面折中考虑。 Followed by a more flexible device operating time; for key equipment, need to punish or reward, as well as limit the impact on business caused by users of these two aspects consider a compromise. 最不重要的负载组可以最先限制最后恢复或释放,最关键的负载组将被最后限制而最先释放。 The most important of load groups can be the first to recover or limit the release of the last, most critical load limit and the last group will be the first release. 在本发明的一个具体实现中,可以使用堆栈存储负载组,如图5所示,限制和释放就类比于先入后出(FIL0)堆栈中的进栈和出栈。 In one particular implementation of the present invention can be used stacked memory load group, shown in Figure 5, analogous to restrain and release it into the intake stack after the first (FIL0) stack and the stack. 如果使用指针标识当前的负载用电状况,在满负载的条件下,指针=0 ;在空负载的条件下,指针=N(N为负载组数目)。 If a pointer identifying the current status of power load, under full load conditions, the pointer = 0; at the empty load pointer = N (N is the number of load groups).

[0072] 对于功率需求状态这一维度,需要考虑的是一个典型的工业用电账单不仅针对能量(或千瓦/小时,即kWh)计费,而且还根据用户与电力公司签订的合同针对峰值需求计费。 [0072] For power demand state this dimension needs to be considered is a typical industrial electricity bills not only for energy (or kW / h, ie kWh) charge, but also according to the contract signed by the user and the power company for peak demand billing. 在电力需量到达合同约定的峰值需求之前,就要采取负载限制。 Before the power demand to peak demand in the contract, it is necessary to take the load limit. 如果已经到达合同约定的峰值需求才进行负载限制,往往为时已晚。 If you have reached the peak demand load contract was limited, often too late. 因此,在本发明提供的需求响应策略中,设置两个需求响应门限用于确定功率需求状态,如图6所示。 Accordingly, the present invention provides in the demand response policy, two demand response thresholds for determining a power demand state, as shown in FIG.

[0073] 首先是限制门限(Pshield)。 [0073] The first is the limit threshold (Pshield). 当测量或预测的电力需量(PD)高于限制门限时,就要采取负载限制,因为下一个峰值需求可能超过和电力公司(utility)签订的合同中约定的峰值需求,而这通常会招致电力公司的罚款或者电力供应终止。 When power demand (PD) measurement or prediction is higher than the threshold limit, it is necessary to take the load limit, because the next peak demand could exceed the contract and Power Company (utility), signed the agreement in peak demand, which usually lead to fine power company or the power supply is terminated.

[0074] 其次是恢复门限(Prelease)。 [0074] followed by recovery threshold (Prelease). 当电力需量降到恢复门限之下,并且原先存在负载限制时,则为所述受限制的负载恢复电力供应。 When power demand drops below the threshold of recovery, and when the pre-existing load limit, the load was restricted restore power supply.

[0075] 相应地,功率需求状态的取值可以根据电力需量和预先设置的限制门限和恢复门限的关系进行设置,包括以下3种:电力需量小于恢复门限、电力需量处于恢复门限和限制门限之间、电力需量大于限制门限。 [0075] Accordingly, the value of the power demand state may be set according to the demanded power and the limit threshold and the recovery threshold relationship set in advance, comprising the following three: power demand is less than the recovery threshold, power demand in the recovery threshold, and between limit threshold, power demand is greater than the threshold limit. 需要指出,上述两个需求响应门限考虑到的不仅是风险,还有系统运行的效率。 It should be noted, these two demand response thresholds take into account not only the efficiency of risk, as well as system operation.

[0076] 进一步地,可设置合同峰值需求(Pcontracted),如果用户在合同中针对峰值需求计费,则按照合同约定设置Pcontracted,否则可以按照系统的满负载需求(peak demand)设置Pcontracted。 [0076] Further, the contract may set the peak demand (Pcontracted), if user charging for peak demand in the contract, the accordance with the contract set Pcontracted, otherwise you can set Pcontracted full load according to the system requirements (peak demand). 因此,在本发明的又一个具体实现中,功率需求状态的取值有4种,包括:Η)小于Prelease、大于Prelease且小于Pshield、大于Pshield且小于Pcontracted、大于Pcontracted。 Accordingly, in a further specific implementation of the present invention, the power demand state value of the four kinds, comprising: Η) Prelease less than, less than and greater than Prelease Pshield, less than and greater than Pshield Pcontracted, greater than Pcontracted. 此外,在一个具体实现中,可以将Pshield设置为Pcontracted 的95 %,将Prelease 设置为Pcontracted 的80 %。 Furthermore, in one particular implementation, it may be set to 80% Pshield 95% Pcontracted will Prelease set of Pcontracted.

[0077] 可以看出,将上述三个维度的不同取值结合,可以得到不同的需求情况(demand situation),比如收到电力消息登入时,负载用电状况为电力使用无限制,且功率需求状态为电力需量大于限制门限就是其中一种需求情况。 [0077] As can be seen, the combination of different values ​​of the three dimensions, can be of different demand (demand situation), such as the power received signed message, using the electricity load status of unlimited power, and the power demand state power demand is greater than the threshold limit is one of demand. 当负载组数目为N时,如果功率需求状态有3种取值,共有(N+1) *3*3种需求情况;如果功率需求状态有4种取值,则有(N+1) *4*3 种需求情况。 When the number of the load groups is N, the power demand state if there are three values, a total of (+ 1 N) * 3 * 3 Species demand; if there are four power demand state value, there are (N + 1) * 4 * 3 kinds of demand. 在每种需求情况下,用户可以有3种不同类型的响应行为(response action): (1)无响应行为;(2)对负载组堆栈(如图5所示)中的下一个负载组进行限制(前提是仍然存在可被限制的负载,即指针小于K) ; (3)将负载组堆栈(如图5所示)中最近一个被限制的负载释放(前提是存在已被限制的负载,即指针大于1)。 In each case the demand, the user may have three different types of response behavior (response action): (1) non-responsive behavior; (2) of the load groups stack (shown in FIG. 5) for a load group is limit (if still present load may be limited, i.e., the pointer is less than K); (3) set the load stack (shown in FIG. 5) is a load release recently restricted (if there is a load has been restricted, That pointer is greater than 1). 在图5所示的负载组堆栈中, 重要程度为K的负载组置于栈顶,重要程度为1的负载组置于栈底。 In the group of loads stack shown in Figure 5, the degree of importance is placed on top of the stack of K load group, the degree of importance of a load placed on bottom of the stack group. 需要指出,每种需求情况对应的响应行为都是可配置的。 It should be noted, each corresponding demand response behavior are configurable.

[0078] 经过上述配置,智能电表所具有的需求响应矩阵的示例见表1,共有5*4*3 = 60种需求情况。 Example [0078] After the above configuration, the smart meter having a demand response matrix shown in Table 1, a total of 4 * 5 * 3 = 60 kinds of demand. 该需求响应矩阵在实际应用中可根据不同的需求情况进行配置,用于控制(即限制或恢复)一个或多个负载组的电力使用。 The demand response matrix can be configured according to different needs of the case in practical applications, to control (i.e., limit or restore) using one or more load power groups.

[0079] [0079]

[0080] 表1需求响应矩阵示例 [0080] Table 1 exemplary demand response matrix

[0081] 如果用户不考虑针对每种需求情况进行配置,也可以采用其他形式的需求响应矩阵。 [0081] If the user is not considered to be configured for each demand, it may be employed other forms of demand response matrix. 例如,作为一个保守选项,可以永远无响应行为;作为一个电力公司奖励倾向型的选项,在出现用于限制的电力消息(即电力消息登入)时,总是对负载进行限制;作为一个系统运行倾向型的选项,通过限制或释放负载组使得系统电力需求始终保持在图6所示的Prelease和Pshield这两个门限之间。 For example, as a conservative option, you can always unresponsive behavior; as a type of power companies tend to reward options, when a power message (ie, a power message login) used to limit the emergence of always load limit; as a system tendency type options, by limiting or releasing the load so that the group remains in the system between the power demand and Pshield Prelease shown in Figure 6 the two thresholds. 当然,可以完全由用户配置自身的需求响应矩阵。 Of course, fully configurable by the user's own demand response matrix.
