Research On The Optimal Dispatching Strategy Of Regional Power Grid With Different Types Of Loads

With the increasing shortage of fossil energy and the severe situation of conventional energy supply,research on the development and utilization of renewable energy for power generation has attracted much attention.However,with the rapid increase of installed capacity of renewable energy generation,the difficulty of orderly consumption leads to high abandonment rate of light/wind in the process of generation,and the traditional "source follows load" dispatching mode does not give full play to the regulation potential of some adjustable loads.To address this problem,this paper focuses on the economic dispatch optimization strategy of power grid,taking into account the diversified characteristics of load-side types and the differences in energy consumption characteristics and demand response potential of different loads,and formulating a more reliable operation strategy for regional power grids with different load types.This paper first introduces the concept and classification of demand response,and analyzes the principles and mathematical models of various distributed power sources in the grid system to provide the corresponding mathematical theoretical basis for the subsequent research.Based on the optimal scheduling of residential loads,the proposed strategy proposes a hierarchical optimal scheduling strategy that takes into account demand response and carbon emission credits.The results show that the consideration of carbon emission factors can better promote the green and economic operation of the grid.For industrial loads,we first analyze the electricity consumption characteristics and demand response potential of each industry,and then propose an optimal dispatching model combining demand response and shared energy storage,taking into account the complementary nature of industrial customers’ electricity consumption and the ability of building energy storage plants to avoid wind and light abandonment.The results show that access to energy storage plants after demand-side management by customers can promote new energy consumption,improve the economy and reduce the pressure of grid peaking.For commercial loads,we propose an optimal dispatching strategy that includes energy storage air conditioners and electric vehicles,and the simulation verifies that the reasonable use of the energy storage characteristics of electric vehicles and air conditioning systems can significantly improve the economy of grid operation.In this paper,we analyze the load characteristics and fully exploit their demand response potential,and propose an optimal dispatching strategy for regional power grids with different types of loads.Figure[47] Table[15] Reference[80]...
