塔式太阳能热发电站的输出与储热调峰特性研究OA

With the increase of the peak valley difference in the power grid,the demand for peak-shaving power sources also increases.Tower CSP stations have good dispatch ability and are high-quality green peak-shaving power sources.This paper takes a 50 MW tower CSP station in Qinghai Province as the study object of commercial operation,and analyzes its components,operating mode,output characteristics,and thermal storage peak-shaving capacity.The analysis results show that:1)The tower CSP station can overcome the randomness and volatility of PV power generation and wind power,and can maintain stable high-power output even in cloudy weather.At the same time,it can also maintain low-power continuous operation according to electricity demand,demonstrating good energy regulation ability.2)The tower CSP station can quickly reduce power during peak periods of PV and wind power generation.When PV and wind power generation are at their peak,they can quickly increase power and maximize the grid's consumption of PV and wind power.
