Calculation method based on peak and valley period electrical load weights

Abstract

The invention discloses a calculation method based on peak and valley period electrical load weights. The electrical periods of the 10KV bus tip, the peak, the valley and the flat of a power grid are calculated; 10KV bus load information and historical load data are split into a 10KV switch outgoing line in different periods, 10KV switch outgoing line load information and historical load data are split into a distribution room transformer in different periods, according to electrical types, distribution room transformer load information and historical load data are split into corresponding class power consumers in different periods, and corresponding load weights are calculated; according to the corresponding class power consumers, load information and historical load data are split into the power consumers in different periods; according to a power grid topological relation, the weights of loads in different periods of the power consumers are calculated; the weights in the tip electrical period, the peak electrical period, the valley electrical period and the flat electrical period of the power consumers serve as electrical parameters of virtual energy accumulation control technology, and the electrical loads are controlled in a peak shifting mode. Accurate prediction of the load peak and valley periods of the regional power grid is achieved, electricity consumption of the peak period of the power grid can be directionally reduced, and electricity consumption of the valley period of the power grid is increased.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to a calculation method based on the weight of electric loads during peak and valley periods. Background technique [0002] At present, the known peak and valley periods of electricity load are set by the power system according to the change law of the total load curve. The peak and valley periods of electricity load cannot be done accurately, and the error of each regional power grid is unavoidable, resulting in regional peak shaving and filling. The valley effect is less targeted. [0003] Demand-side management: with the support of government regulations and policies, effective incentives and guidance measures and appropriate operation methods are adopted, through the joint efforts of power generation companies, power grid companies, energy service companies, social intermediary organizations, product suppliers, and power users , improve the efficiency of termina...

Problems solved by technology

[0006] The purpose of the embodiment of the present invention is to provide a calculation method based on the load weight of peak and valley periods, aiming to solve the problem that the current known peak and valley periods of electric load are set by the power system according to the change law of the total load curve. It is impossible to be accurate during the peak and valley periods of electric load, and it is inevitable to make errors in the regional power grids, resulting in the problem of poor pertinence in the effect of regional peak shaving and valley filling
