清洁能源跨省跨区消纳交易机制可行性及效益分析

Feasibility and Benefits Analysis of Trans-provincial and Trans-regional Clean Energy Consumption and Transaction Mechanism

近年来,中国环境治理和能源供给形势依然严峻。发展清洁能源和能源合理配置是缓解目前环境能源严峻形势的战略措施。然而目前由于中国步入经济新常态,电力需求放缓,清洁能源装机仍保持较快增长,"三北"地区可再生能源消纳及弃风弃光问题愈加严重。在新一轮电改快速推进的背景下,完善清洁能源跨省跨区消纳和交易机制,提高受端地区接纳清洁能源的积极性是近期缓解"弃风弃光"问题的主要措施。提出了通过跨区发电权交易将省内机组部分基数电量计划以一定价格转让给西部电厂发电的新机制,得出了该机制下实现交易主体经济共赢的条件。并从西部装机现状、交易通道和可交易量三方面深入分析了该交易机制的可行性。最后以华东某火电厂和西北某新能源电厂为例,从交易方式和收益分析等方面进行了算例分析,分析结果表明该机制在满足共赢条件下能实现交易主体在经济效益和社会效益上的双共赢。

In recent years, the situation of environment treatment and energy supply are still severe in China. Developing clean energy and disposing energy properly are strategic measures to alleviate the serious condition of energy and environment. But due to the new circumstances of economy in China, the demand of electricity has slowed down. However the capacity of clean energy has maintained rapid growth, the consumption of renewable energy in ＂ three north＂ area has become a problem and the abandon of wind and solar power is more serious in China. In the new round of power system reform, it is important to com-plete trans - provincial and trans - regional consumption and transaction mechanism of clean energy to stimulate the initiative of receiving power grid to consume clean energy, which will solve the serious problem mentioned above. A new transaction mechanism is proposed which is to transfer certain capacity of base power generation plan from local power plan to western power plan at certain price through trans - regional generation right trade. The condition for transaction subjects to achieve win -win is obtained. Further the feasibility of transaction is studied deeply as viewed from western power generation installation status, transaction channel and potential transaction capacity. Taking some thermal power plants in East China and some new energy power plants in northwestern area for example, transaction simulation is carried out in transaction pattern, benefit anal-ysis and so on. The results of transaction simulation show that the mechanism can achieve win - win of all transaction subjects in both economic benefits and social benefits under the condition mentioned above.
