基于电力市场改革的典型微网经济分析

Economic Analysis of Typical Micro-grid Based on the Electricity Market Reform

作为分布式能源发展的阶段产物,微网对分布式电源的有效利用以及对大电网的有效补充,其可行性已得到充分的论证。随着电力改革的推进,微网作为允许的潜在的新售电主体,以其经济效益代表的生命力引起了电网企业以及第三方投资者的广泛关注。构建了并网型及离网型四类典型的分布式能源的配置方案,并通过微网全生命周期内的经济测算,分析了不同类型的微网的经济效益,并结合售电侧市场化改革趋势,提出了未来微网的运行模式。

As the stage product of the distributed energy-development, the micro-network is an effective use of distributed energy as well as an effective complement to the big power grid, its feasibility has been adequately demonstrated. With the advance of electrici- ty reform, as the new permitted electricity sales principal, micro-grid- economic benefits have attracted widespread attention of grid companies and third-party investors. The paper builds four typical configuration schemes of distributed energy including join-grid mi- cro-grid and off-grid micro-grid, then analyzes the economic benefits of the different types of micro-grid by the economic estimates in full lifecycle. Finally, future micro-grid operational mode is proposed with combining the market reform of electricity sales side.
