Abstract

Large scale wind power integration has a negative influence on the frequency response. Assistant measurement improves the frequency stability of power systems under high wind penetration. The Proportional Curtailment Strategy (PCS) for wind turbines provides a primary frequency reserve for power systems. To solve the worthless curtailed wind power, the PCS is used to improve the utilization of wind power curtailment. Then the wind turbine and the lithium battery Energy Storage System (ESS) provide primary frequency reserves together. Different control strategies of ESS have been proposed based on the different methods for selecting valid reserves. The economic benefits of different control strategies have been compared based on the same frequency regulation reserve. The optimal control strategy is the maximum method. The economic benefit of the maximum value method is ¥4,445,300.

Highlights

In recent years, fossil fuels such as coal, oil, and so on are drying up all over the world
In [22], this paper proposes the concept of the virtual energy storage system (VESS), which includes conventional energy storage systems, flexible loads, distributed generators, multi-vector energy systems, and so on
In order to realize the control method with more beneficial effects, this paper proposes two control strategies to participate in the primary frequency regulation for the energy storage system and the wind farm

Summary

Introduction

Fossil fuels such as coal, oil, and so on are drying up all over the world. In [1,2,3,4], the problems of climate warming and environmental pollution are becoming more and more serious. In this context, the generation of renewable power has developed rapidly. Wind power is representative of renewable energy. The cumulative installed capacity of global wind power has grown at a remarkable rate between 2005 and 2017, averaging near 22% per annum. The Chinese wind power industry started late, it has developed rapidly with the support of the “renewable energy law” and other related policies. In June 2012, Chinese wind power installed capacity had exceeded the United
