摘要
在分析微电网特点的基础上,提出了基于多代理系统(multi-agent,MAS)的微电网电力市场交易模型。考虑到电力市场是一个不完全竞争市场,应用博弈论对微电网竞价策略进行分析。由于微电网的特殊性,微电网本身可以看成一个小型的低压配电网系统,而对于上级电力市场,微电网可以看成一个发电商,微电网要实现自身经济效益最大化就需要从这2个方面进行优化。应用等微增率对微电网各发电元件的经济运行进行分析计算,通过算例计算,得出了微电网自身利润最大化的报价策略和最优化运行方案。
Based on the analysis of micro-grid character,micro-grid power market bidding model based on MAS is proposed.Considering the fact that the electricity market is not a perfectly competitive market,we apply game theory to the analysis of bidding strategy of micro-grid.However,micro-grid has great difference with traditional power plants.Micro-grid itself can be regarded as a small,low-voltage power distribution system,and for higher power market can be viewed as a power producer.To get the best profit,micro-grid bidding strategy in electricity market and dispatching its generators in economic mode are needed.So we use equal incremental rate to optimize the output of each power generation components of micro-grid in this paper.Finally,an example is calculated to get bidding strategy solution that micro-grid is expected to maximize the economic benefits and optimal operation scheme.
