Source-load Cooperative Operation Strategy of Integrated Energy Service Provider Based on Wind Power Accommodation Demand

Abstract

In the future, wind power will enjoy the same output level as thermal power and undertake certain system regulation tasks at the same time. Large-scale wind farms urgently need to find a new way to improve their accommodation levels. Promotion of energy internet and opening of power-sale-side provide an environment and opportunity for integrated energy service provider (IESP) to aggregate multiple types of energy-supplied equipment and comprehensive flexible loads to directly meet the demand for wind power accommodation. Based on analysis of current status of wind power operation in China, this paper discusses the accommodation demand of schedulable wind farms. A wind farm-IESP cooperative operation mode (WICOM) based on wind power accommodation demand is proposed considering the response capability of self-operated equipment of IESP, controllability of integrated demand response load and elasticity of heating load in jurisdictions. Then a comprehensive response model of the IESP is constructed, and a day-ahead economic dispatch model is established with the goal of maximizing IESP's revenue. Finally, simulation validates the positive role of WICOM in improving income of IESP and accommodation level of wind power.
