Embodiment Construction

[0087] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0088] Such as figure 1 As shown, a demand response effect evaluation method with load limit as the target includes the following steps:

[0089] Step 1, determine the demand response assessment time.

[0090] Demand response assessment time includes response time and bounce time, such as figure 2 As shown, in the figure T s For the response start time, T f is the response end time, T f -T s is the response time and T f -T s =nΔt, n is the number of response periods within the response time, Δt is the time of one response period, T end is the end time of load rebound, T end -T f is the rebound time.

[0091] Step 2, with the load limit as the goal, determine the three major evaluati...

Abstract

The invention discloses a demand response effect evaluation method by taking load limit as the goal. The method includes the following steps that firstly, demand response evaluation time is determined; secondly, three evaluation sub-goals are determined by taking load limit as the goal; thirdly, a demand response effect evaluation system by taking load limit as the goal is established according to the judgment standard whether the evaluation sub-goals are strongly correlated; fourthly, per-unit disposal is conducted on important evaluation indexes and auxiliary evaluation indexes, the percentage of each evaluation index is worked out, and the weighting method is adopted for unified solving to obtain an evaluated value. The evaluation method has comprehensiveness, independence, easy measurement, flexibility and practicability, needed data are obtained conveniently and are easy to understand, solving is conducted through the weight factor method, engineering application is facilitated, and the method plays a role in filling the blank in the aspects of demand response/orderly power utilization effect evaluation or demand response allowance standard formulation.

Description

technical field [0001] The invention relates to a demand response effect evaluation method with load limit as the target, and belongs to the technical field of electricity service. Background technique [0002] Under the dual influence of the contradiction between power supply and demand, the cost of traditional peaking units, and the environment and resource constraints, demand-side resources are becoming a new element of power grid dispatching. Compared with conventional power generation resources, demand response resources have certain advantages in participating in power grid operation control. For example, when conditions permit, demand response resources can quickly respond to scheduling and control instructions, and the capacity of demand response resources after aggregation is adjustable and flexible; At the same time, due to the relatively scattered distribution of demand response resources, they can be optimized and aggregated from the network and geographical leve...
