Study On Source And Load Coordinated Scheduling Strategy Based On Demand Response Including Wind Power Accommodation

As a clean and renewable energy,wind power develop rapidly under the background of energy crisis and the deterioration of environment.High penetration of wind power poses great challenges on power system operation due to its uncertainty and intermittency.The development of microgrid can ease the difficulty of integration of wind power.It can calm part of the fluctuations through complementary characteristics and the use of energy storage device,but it cansignificantly reduce operation economy of the system.So we need to change the traditional pattern of scheduling and improve ability of flexible scheduling.Demand response is an important interactive resource of smart grid,and can rapidly response requirement.So demand response become an important way to accommodate wind power.The study of the paper is source and load coordinated scheduling strategy of wind power accommodation based on demand response.It aims to improve the capacity of wind power accommodation through the bidirectional interaction of supply side and demand side resources.In this paper,it chooses critical peak pricing and interruptible load aiming at industial users and uses scenario analysis method to simulate wind power.It analyze the unit,storage devices and flexible load.Considering the characteristics of wind power prediction error,it establish economic scheduling model of two stages of a few days ago and days.Then,in this paper,it selects real-time pricing and direct load control aiming at the residential users involved in the system scheduling,and establish multiple target of source and load coordinated scheduling model from the angle of the grid benefit,customer satisfaction and environment.It becomes fuzzy multi-objective model,and convert into a single objective problem using maximize satisfaction index method.Example analysis proves the rationality and validity of the model.R esults show that different users choose their suitable mechanism of demand response,and the supply side and demand side resources can be flexible interaction,so as to improve the capacity of wind power accommodation,optimize the load curve,reduce operation costs,and have a certain role in promoting energy saving and emission reduction.This research provides reference to explore optimal operation of promoting wind power accommodation through demand side resources for the future.
