南方(以广东起步)电力现货市场机制设计

Mechanism Design of Southern China ( Starting from Guangdong Province) Electric Spot Market

遵循市场经济基本规律和电力工业运行客观规律,综合考虑广东电网的实际情况,本文设计了南方(以广东起步)电力现货市场机制,提出了以基于差价合约的中长期交易规避风险和全电量集中竞争现货交易发现价格的电力市场交易体系,设计了基于节点电价的两部制结算方法。将原有中长期物理交易变更为中长期差价合约交易,增加了交易种类和交易频次,有利于提高市场流动性,全电量申报、集中优化出清的日前、实时市场,可形成反映电力系统物理运行特点的电能价格信号,促进资源配置优化。

Following the basic laws of the market economy and the objective laws of the operation of the power industry ,considering the actual situation of the Guangdong power grid,the southern China (starting from Guangdong) electric spot market is designed. The electric spot market system consists of medium-term and long-term trading based on contract for Difference (CFDs) for hedging risks and centralized spot market for price discovery. Two settlement mechanism based on locational marginal price is applied. The designed spot market system changes the original medium-term and long-term trading based on physical transactions to that based on CFDs,with increased transaction types and transaction frequency,which helps to improve market liquidity. Centralized spot market ,including day-ahead and real-time markets,can form a power price signal reflecting the physical operation characteristics of the power system,and promote resource allocation optimization.
