Dispatch Studies Of Demand Response In Source Network Load Interaction Mode Of Active Distribution Network

With the development of wind energy,solar heating and other clean energy,the old electric power structure has undergone great changes.In the current context of further deepening the reform of electric power,Executive meeting of the State Council put forward the "transmission and distribution release,scheduling independent marketing electricity side open,platform independent," these four initiatives.In order to comply with the current background of the electric power system,based on the current active demand response in power distribution network based on the in-depth understanding of the application.To Advance a demand response in an active power source network load application in interactive mode subject.Based on this subject,made the following studies:Study on active power convex relaxation of second order transformation model of optimal power flow problem.This model can significantly reduce the amount of initiative to optimal power flow calculation of distribution networks,For demand response in active distribution network for Dutch interactive mode provides the mathematical basis for the application.In order to optimize power supply side as the starting point,to study active distribution network optimization scheduling problem with demand response of convex relaxation of second order based on transformation,constructs a mathematical optimization model including demand response,analysis of demand response participation in active distribution network scheduling problem with user side effects;optimization as the starting point.In response to the scheduling problem of real-time price demand based on the maximization of social welfare under the background of household electricity,analyzes the different family load and energy storage device and demand response effect on the scheduling problem consists of electric vehicle,the TOU price under the background of demand response and energy storage device with a peak effect.The profit Matlab software is used to calculate and analyze the example of the above three cases,and the scheduling scheme under different conditions is given.The results verify the correctness of the theoretical analysis in this paper.
