海上風電對廣東省電力現貨市場的影響性分析 ——《粵港澳大灣區綠色發展報告（2020）》

 

摘 要：

南方(以廣東起步)電力現貨市場已經正式開始試運行。為緩解廣東省供電壓力以及發展清潔能源，截至2021年，廣東省欲規劃海上風電共計302萬千瓦。鑒於風電機組的出力特性和現貨市場的出清原則，海上風電的接入將對廣東省電力現貨市場產生重要影響。本文通過簡化的廣東省電力系統模型，對2019年至2021年的現貨市場進行仿真，進而研究海上風電的並網對現貨市場的影響。結果表明，2019年至2021年，接入海上風電與未接入海上風電的情況比較，系統節點電價會顯著降低；當系統發電側傳統電源的增長速度趕不上負荷側需求增長的速度時，系統節點電價會逐年上升。就目前廣東省海上風電的發展規劃而言，未來三年海上風電的並網並不會造成嚴重的系統阻塞。

The Impact of Integrating Offshore Wind Power in the Guangdong Electricity Spot Market

Song Yi, Lin Chenyun, Liang Gaoqi, Zhao Junhua

 

Abstract: The Southern (starting in Guangdong) spot market has officially started trial operation in 2019. In order to alleviate the pressure on power supply and develop clean energy resources, Guangdong will build 3.02 million kilowatts of offshore wind power by 2021, which will have a major impact on Guangdong electricity market due to the output characteristics of wind turbines and the clearing regulation of spot market. We used the simplified Guangdong power system model to simulate the Guangdong electricity market from 2019 to 2021, and then analyzed the impact of offshore wind power on the Guangdong market. The experimental results show that integration of offshore wind power would reduce the locational marginal price. When the growth rate of stable power generation of the whole system cannot meet the growth of demand on the load side, and the price of electricity will increase year by year. In addition, the integration of offshore wind power in the next three years would not cause significant system congestion.
