摘要
我国电力市场正处于深化改革阶段,输电网络运营环境复杂,输电阻塞问题日益受到关注。首先,采用阻塞定价法和阻塞修正法对阻塞管理市场机制进行分类,并总结了国外典型电力市场中的阻塞管理方法。然后以英国及澳大利亚电力市场为例分析阻塞管理机制对发电商合约收益的影响,相关算例分析结果表明,阻塞管理对合约收益的影响主要在于是否对限下机组进行补偿。最后对我国电力市场阻塞管理机制提出建议。
With the deepening of electric power market reform in China, the transmission network is in a complex operating environment and transmission congestion is increasingly attracted attention. Firstly, market mechanisms for congestion management are classified by congestion pricing method and congestion correction method; secondly, congestion management methods of overseas typical electricity markets are summarized.Finally, the impact of the congestion management mechanism on the contract revenue of power producers is analyzed based on the UK and Australia power market. The relevant case analysis shows that the impact of congestion management on contract revenue is mainly based on whether there is compensation for the constrained-on units. At the same time, some suggestions on congestion management mechanism of the power market in China are put forward.
