基于电源规划模型的市场限价与容量补偿机制衔接分析OA

Due to the extensive integration of renewables,there has been a decrease in market clearing prices,concurrently reducing the operational hours of conventional generators.Additionally,the relatively low market price cap in China makes it challenging to recover fixed costs associated with conventional generators,thereby compromising the reliability of the power supply system.Against this backdrop,investigating the relationship between the market price cap and capacity remuneration costs becomes crucial,as it directly impacts the effectiveness of market mechanisms and the maintenance of power system reliability.Therefore,this study employs a capacity expansion model to analyze the inherent connections between power system reliability and the market price cap,as well as the capacity remuneration mechanism.The unit cost function is constructed to analyze the influence of market price caps and capacity remuneration mechanism on power supply structure.Finally,the study conducts a case study based on the net load of a provincial-level power grid,revealing the relationship between capacity remuneration and the market price cap under given levels of power supply reliability.Furthermore,it concludes that capacity remuneration mainly affects the installed capacity of peak generators.
