Abstract

The invention aims to provide an economy scheduling model based on price demand response. The model is firstly based on the price elasticity coefficient to analyze the relationship between the price demand response scheduling cost and the interactive response quantity. Then, the interactive response quantity's static algorithm of the price demand response is described and used as one of the desired allocation rules. Based on that, in consideration of the network security constraint and the price demand response and the interactive response satisfaction constraints, the power grid side price demand response scheduling cost is used as the smallest goal, and a real-time optimization scheduling model is created to ensure the safe operation of the power grid in real-time scheduling.

Description

technical field [0001] The invention relates to an economic dispatch model based on price demand response. Background technique [0002] Wind power is the power generation method with the most economic development prospects among renewable energy sources. However, due to the unfriendly characteristics of wind power itself such as volatility, intermittency, anti-peak regulation, and low dispatchability, the rapid growth of its installed capacity has a negative impact on the traditional power grid. have a significant impact on the operational control mode. In order to cope with this challenge, the power supply, power grid and load should coordinate and interact, which is an important development direction of smart grid. But in general, the power grid operation control mainly adopts the power generation tracking load mode, and meets the forecasted load demand by scheduling the start-up and shutdown of generator sets and output. But when large-scale wind power is connected to ...
