促进新能源消纳的自备电厂发电权交易模式可行性探讨

随着中国西部地区新能源的大规模快速发展,电网消纳与外送能力不足、调峰能力缺乏等问题日益凸显,导致弃风弃光现象严重。针对当前甘肃相当规模的自备电厂未充分参与电网调峰的问题,提出在现有电力市场交易政策框架内实际可行的自备电厂与新能源企业间的发电权转让交易模式,以此促进自备电厂承担公用调峰职责,提升电网调峰消纳能力。通过现状论述、政策调研分析交易模式的可行性,建立自备电厂与新能源的发电权交易模型,双方在市场机制下可达到利益平衡,实现共赢。所列举的成功试点验证了该交易模式可有效推动新能源电量消纳与平衡,减少弃风弃光,为电力体制改革和电力市场建设中的新能源消纳和发电权交易提供了实践依据和示范。

Feasibility Analysis of Trade Mode Promoting New Energy Consumption Based on Generation Rights Trade of Self-generation Power Plants

With the rapid and large-scale development of new energy in west of China, the lack of new energy power transportation or consumption, and the shortage of grid peak-shifting ability have become increasingly serious, leading to severe wind/photovoltaic power discard. Aiming at the issue that numerous self-generation power plants have not fully participated the grid peak regulation, this paper presents a generation rights trade mode between self-generation power plants and new energy enterprises under current policy framework of electricity market, in order to promote self-generation power plants to fulfill the peak-shifting responsibility of public generation plants, and enhance grid peak regulation ability. By analyzing policies and status of the trade mode, this paper establishes the numerical model of the generation rights trade between self-generation power plants and new energy enterprises, then gives out the profits balance and win-win conditions. Also, this paper illustrates the successful pilot projects of Gansu Jinchuan Group Co. Ltd. and Lanzhou Branch of China Aluminum Co. Ltd. , which verify the validity of the trade mode in new energy power consumption and decrement of discarded wind/photovoltaic power. The work provides practical foundations and demonstrations for the new energy consumption and generation rights trade in electric power system reform and electricity market construction.
