Control and charge calculation method for power grid power load peak shift in short supply situation

Abstract

The invention relates to a control and charge calculation method for power grid power load peak shift in a short supply situation, and belongs to the technical field of power grid power control. The control and charge calculation method for the power grid power load peak shift in the short supply situation comprises the steps that power consumers submit data of power consuming curves and data of peak shift quotation curves to a power grid company; the power grid company builds a power load peak shift optimizing model according to the data, submitted by the power consumers, of the power consuming curves and the data, submitted by the power consumers, of the peak shift quotation curves; the power load peak shift optimizing model is solved to obtain an optimum control plan of the power consumer peak shift, and peak shift control signals are sent to all the power consumers; the power consumers carry out load peak shift according to the peak shift control signals sent by the power grid company; after power load peak shift is completed, charges of the power consumers involved in the peak shift are shared by power consumers not involved in the peak shift. The control and charge calculation method for the power grid power load peak shift in the short supply situation can improve evenness of the spatial and temporal distribution of power load, and thus power resources are made to be utilized more sufficiently. Precision control of the power grid company over the power consumer peak shift according to needs can be achieved, and the control and charge calculation method for the power grid power load peak shift in the short supply situation has important practical significance and good application prospects.

Description

technical field [0001] The invention belongs to the technical field of grid electric power control, and in particular relates to a control and cost calculation method for power load peak shifting under the condition that the grid is in short supply. Background technique [0002] Demand side management (DSM) refers to the planning and measures formulated by power companies to influence the power consumption mode of power users and improve the uniformity of power load distribution in time and space. In the 1970s, in order to deal with the energy crisis, the United States began to adopt management measures to curb energy consumption. In the 1980s, it gradually evolved into a load control method of shaving peaks and filling valleys. By 1984, the American Electric Power Research Institute (EPRI) clearly proposed the concept of demand side management for the first time (Clark W G. Then and now: The perspective of the man who coined the term 'DSM' [J]. Energy Policy, 1996, 24 (4),...

Problems solved by technology

In this method, the power user’s peak shifting cost is borne by the power grid company, and the power user will tend to quote a high price, which will cause the power user’s peak shifting quotation to deviate from its real peak shifting cost; while the power user’s real peak shifting cost is the power user’s The private information of the grid company cannot be obtained

In the case of information asymmetry between the power grid company and the power user, this method cannot solve the problem of the deviation between the peak shifting quotation of the power user and the real peak shifting cost
