摘要: 随着清洁能源的快速发展,微电网凭借其对分布式电源灵活高效的集成能力,已成为智能电网的重要发展方向。电力市场环境下,微电网如何协调优化好内外部资源,取得最大经济利益对其生存和发展至关重要。为有效促进电力市场环境下微电网的经济优化运营,提出了电力市场环境下的微电网双层经济调度优化模型。模型中上层考虑微电网参与售电侧市场和电力辅助服务市场竞争,制定微电网市场交易计划,优化微电网运营收益;下层考虑微电网内部分布式电源优化调度,协调内部各种资源最优分配,使运行总成本最低。通过算例分析验证建立双层优化,微电网可在电力市场竞争环境下获得更好的经济效益。

Abstract: Along with rapid development of clean energy and relying on its flexible and efficient integration capability for distributed generation, the microgrid has become an important development direction of smart power grid. In the environment of electricity market, it is extremely important that how microgrid can well coordinate and optimize its internal and external resources to gain maximized economic benefit for its existence and development. To effectively promote economic and optimized operation of microgrid under the condition of electricity market, a bi-level economic dispatching optimization model for microgrid was proposed. In the upper level of the proposed model, following items such as making the microgrid participate the competition in the selling side of electricity market and the ancillary service market, drawing up the market trading plan for microgrid, optimizing the operation income of microgrid and so on were considered; in the lower level of the proposed model following items were considered: the optimized scheduling of distributed generations within the microgrid, coordinating the optimal allocation of various internal resources to make the total operation cost the lowest. It is verified by analysis results of computation example that by means of establishing bi-level optimization the microgrid can obtain better economic benefit under the competition environment of electricity market.
