考虑能量存取的自备电厂去中心化交易机制探究

传统发电权交易模式下,交易价格需要满足一定的条件才能驱动自备电厂参与新能源消纳,无法充分释放自备电厂的调峰潜力,且在中心化交易系统下,存在运维成本高、交易效率低等问题。为此,文章提出了自备电厂的能量存取服务模式,扩大新能源消纳空间,并采用去中心化交易机制提高交易效率。同时,构建了去中心化的交易撮合模型,以新能源最大化消纳和能量存取服务费用最小为目标,综合考虑电厂企业利益、机组电量空间、新能源消纳需求及电网安全等约束条件,对发电权和能量存取交易进行配比优化。算例分析表明,自备电厂通过提供能量存取服务,能够有效提升新能源的消纳量,提高市场整体的经济效益,为完善新能源消纳机制提供有益参考。

Research on Decentralized Transaction Mechanism of Self-Contained Power Plant Considering Energy Access Service

Under the traditional trading model of power generation rights, the transaction price needs to meet certain conditions to drive the self-contained power plant to participate in new energy consumption, which cannot fully release the peak-shaving potential of the captive power plant. Moreover, under the centralized transaction system, there are problems such as high operation and maintenance costs and low transaction efficiency. The energy access service model of self-contained power plants is proposed to expand the space for new energy consumption and adopt a decentralized transaction mechanism to improve transaction efficiency. At the same time, a decentralized transaction matching model is constructed. With the goal of maximizing the consumption of new energy and minimizing the cost of energy access services, it comprehensively considers the constraints of power plant interests, unit power space, consumption space and grid security, and builds an optimization model for power generation rights and energy access power. Analysis of calculation examples shows that by providing energy access services, self-contained power plant can effectively increase the consumption of new energy, improve the overall economic benefits of the market, and provide a useful reference for improving the mechanism of new energy consumption.
