【摘要】：智能电网的发展使得分布式电源得以顺利接入电网,而这正在改变着电网公司垄断供应电能的市场格局。本文运用博弈论的方法,系统的研究了分布式发电商参与电力市场竞争后带来的影响,建立了包含商业用户、工业用户、居民用户三个电力市场以及不同能源生产技术的市场均衡模型,刻画了市场结构从垄断到寡头垄断,再到垄断竞争的演变过程,并给出了算例。研究发现,随着竞争的加剧,电力市场总交易量大幅增加,平均电价、传统供电商的产量和利润均大幅下降,价格需求弹性较高的工业用户市场价格下降了98%。在智能电网的发展过程中,要充分估计传统供电商在分布式发电并网中的阻力,但在设计电力市场时,避免过度竞争导致的发电投资不足。
[Abstract]:With the development of smart grid, distributed generation can be connected to the grid smoothly, which is changing the market pattern of power supply monopolized by grid companies. This paper systematically studies the influence of distributed generators after participating in the competition of electricity market, and establishes a market equilibrium model which includes three power markets, commercial, industrial and residential, and different energy production technologies. This paper describes the evolution of market structure from monopoly to oligopoly, then to monopoly competition, and gives an example. The output and profits of traditional power providers have both dropped substantially, and the prices of industrial customers with high price elasticity have dropped by 98%. In the development of smart grids, the resistance of traditional power providers in distributed generation and grid connection should be fully estimated. But in designing the electricity market, avoid underinvestment in generating electricity caused by excessive competition.
