大湾区电力现货市场建设路径及出清模型

Construction Path and Market Clearing Model of Electricity Spot Market in Greater Bay Area

区域统一电力现货市场对于促进电力资源在更大范围内的优化配置、促进可再生能源跨区消纳等方面具有重要作用。以南方区域电力现货市场为基础,构建粤港澳大湾区统一电力现货市场,对于优化港澳电源结构、降低大湾区用电成本、提高港澳系统运行可靠性等方面具有重要作用。然而,粤港澳大湾区的经济制度、法律体系和行政体系存在巨大差异,决定了当前电力资源并不能在大湾区完全自由流动,直接建成粤港澳大湾区统一电力市场具有相当大的难度。本文以统一电力现货市场为研究对象,结合大湾区现状,研究提出大湾区统一电力现货市场的市场模式和建设路径,提出区域起步阶段、分散协调阶段和统一分级阶段的出清数学模型,及第二阶段出清求解方法,为大湾区统一电力市场建设提供参考。

The regional unified electricity spot market plays an important role in promoting the optimized allocation of power resources in a wider range and promoting the cross-regional consumption of renewable energy.Based on the Southern China Regional Electricity Market,building a unified electricity spot market in the Guangdong-Hong Kong-Macao Greater Bay Area will play an important role in optimizing the power structure of Hong Kong and Macao,reducing electricity costs in the Greater Bay Area,and improving the reliability of Hong Kong and Macao power system operations.However,there are huge differences in the economic,legal,and administrative systems of the Greater Bay Area,which determines that current power resources cannot completely flow freely in the Greater Bay Area.It is quite difficult to directly build a unified electricity market in the Greater Bay Area.This paper takes the unified electricity spot market as the research object.Firstly,it compares and analyzes the characteristics of typical foreign regional market models and the adaptability to the Greater Bay Area spot market.Secondly,based on the status quo of the Greater Bay Area,the market model and construction path of the unified electricity spot market in the Greater Bay Area are proposed,and a mathematical model and solution of market clearing in the initial stage,decentralized coordination stage,and unified stage are proposed.
