Economic Analysis of Grid Parity of Centralized Photovoltaic Power Plants in Different Regions
摘要
Abstract
[Objectives]Based on the background of photovoltaic power generation without policy subsidy parity,the comprehensive analysis of the economic feasibility of grid parity for centralized photovoltaic power stations can provide a reference for economic optimization.[Methods]The process of economic evaluation of centralized photovoltaic power station and the accurate calculation method of critical point are studied,that is,the programming recursive calculation is used to replace the traditional fitting curve method.This paper puts forward the judgment method of whether the photovoltaic power station can be put on the grid at par,that is,whether the feed-in price at the critical point is lower than the regional coal-fired benchmark price.Taking a 65.59 MW centralized photovoltaic power station in Xinjiang as an example,the economic analysis is carried out to verify whether the judgment method is reasonable.[Results]The algorithm enhances the accuracy of critical point calculations.Building upon this,an analysis of the overall situation and cost-effectiveness trends of grid parity in China is conducted.The findings suggest that centralized photovoltaic power stations in China can essentially achieve grid parity,with the central regions exhibiting the best economic benefits.[Conclusions]Using critical point analysis to determine if a power station can achieve grid parity will help assess the station's resilience to risks,assist businesses in making informed decisions to achieve cost reduction and efficiency improvement.关键词
