Abstract
Due to its considerable energy storage and peak shaving capabilities,Concentrating Solar Power(CSP)is a promising form of renewable energy power generation.CSP stations are different from conventional thermal power plants in that its heat collection system and heat storage system investment is relatively high,and the unit usually does not operate continuously.Restricted by water resources,at present,the main cooling system of CSP stations in China mostly adopts direct air cooled condenser(ACC)system.Configuration of ACC system will have exact impact on economy and profitability of the unit.On the premise of summarizing and analyzing the investment composition and operating characteristics of CSP stations,this paper relies on a case project to carry out ACC system optimization calculation and analysis.The selection and processing of meteorological data of direct air cooling system of CSP station and the sensitivity analysis of electricity price are discussed.Since the on-grid electricity price and cost electricity price are both high,compared with ACC system of thermal power plants,the ACC system configuration of CSP stations tends to be a scheme with lower initial temperature difference(ITD)value,lower wind speed,and larger air condenser area.关键词
