A Method to Evaluate Comprehensive Benefits of Hybrid Wind Power-Pumped Storage System
摘要
Abstract
In allusion to restricted grid-connected capacity and high wind power curtailment when large-scale wind farm is grid-connected, in usual it is considered to improve power grid’s ability of accommodating wind power by energy storage system, however how to evaluate the overall efficiency of the hybrid wind power-pumped storage system is the problem to be solved well. For this reason, the investment cost, economic benefit of pumped storage system and its operational constraints are analyzed, thus the follow-up mechanism between comprehensive benefits of hybrid wind power-pumped storage system and energy storage capacity under optimized operating condition of regional power grid is revealed, and a mathematical model to solve the comprehensive benefits is established and a method to evaluate the comprehensive benefits is proposed. Based on output curves of mutually matched thermal generation units, wind power and load characteristics of power grid and combining with the installation capacity of thermal generation units and utilizing the incidence relation between system frequency and load (or the change of power generation), the proposed method quantitatively analyzes the impacts of the change of such factors of pumped storage station as its capacity, service life, cost and revenue on comprehensive benefits and power grid’s accommodation ability of wind power. Case analysis shows that proposed evaluation method is effective.关键词
