Control method for reducing grid system peak value average load rate

Abstract

Disclosed is a control method for reducing a grid system peak value average load rate. Each customer conducts electricity demand response to an electricity price published by an electrical supplier so as to obtain maximized profit (the profit is defined as cost difference of electricity utilization benefit and electricity utilization paying). The electrical supplier decides the real-time electricity price according to predicted response of the customers to the electricity price so as to obtain maximum profit. For the customers, based on an aim of the maximized profit, a perfect expression exists between the optimum electricity demand response and the electricity price, and therefore each customer can rapidly reply the desirable optimum electricity demand response through the expression according to the electricity price published by the electricity supplier. For the electricity supplier, the problem of non convex optimization of the electricity price is solved according to a price control algorithm based on simulated annealing. According to the control method for reducing the grid system peak value average load rate, the conditions that an existing grid system is wavy in a large amplitude in electricity consumption between a non peak period and a peak period, and the peak value average load rate is high are effectively avoided.

Description

technical field [0001] The invention relates to a control method for reducing the peak average load rate of a grid system. Background technique [0002] In today's grid, we observe that wholesale electricity prices usually change in real time: because of the high cost of generating electricity during peak electricity consumption, the wholesale electricity price is usually the largest during peak electricity consumption. However, all end-users are now charged an almost uniform retail electricity price, which does not reflect the actual wholesale electricity price. Due to the flat rate, customers typically consume more power during peak hours (such as the time between evening and bedtime for residential customers). This leads to large fluctuations in electricity consumption during off-peak and peak hours. High demand during peak hours not only leads to high generation costs, but also affects the reliability of the grid. In an ideal situation, the electricity supplier hopes ...
