考虑利益主体合作的分布式电源运营商电源优化配置

随着电力市场的不断开放,分布式电源运营商作为新的利益主体进入市场,在主动配电网中由大量分布式电源运营商进行电源配置将成为未来的趋势。如何在电力市场环境下良好地运营,在进行电源优化配置时保证技术经济效益是分布式电源运营商面临的重要问题。针对此问题,文章对分布式电源运营商与配电公司之间的合作关系进行了深入分析,在分布式电源运营商的综合收益中考虑主动管理成本,计及运营期间配电公司实施的主动管理策略,构建了双层电源优化配置模型。上层以分布式电源运营商为主体,以综合收益最大为目标进行电源优化配置;下层以配电公司为主体,以分布式电源切除量最小为目标进行优化运行。建立联合概率场景以计及分布式电源出力及负荷的不确定性,采用改进和声搜索算法与基于过滤集合的内点算法进行模型求解。算例分析结果表明,文章所提双层电源优化配置模型符合电力市场现状,模型中主动管理策略与主动管理费用的引入实现了分布式电源运营商与配电公司的互利共赢,为分布式电源运营商的可持续发展提供了借鉴。

Optimal Power Configuration of Distributed Generation Operator Considering Cooperation of Stakeholders

With the continuous expansion of the power market, distributed generation (DG) operators enter the market as new stakeholders. Large amounts of DG operators configuring the power in active distribution network will become the future trend. It is an important issue for DG operators to operate well in the power market and ensure their economic benefits when configuring DG. In view of this problem, this paper analyzes the cooperation relationship between the DG operators and the distribution company, considers active management fee in the comprehensive profit of the DG operator, takes the active management strategies into account implemented by the distribution company during the operation, and builds a bi-level optimal configuration model of DG. This paper takes the DG operator as the upper body and optimizes the DG configuration with the goal of maximizing the comprehensive profit, and takes the distribution company as the lower body and optimizes the operation with the minimum DG removal amount as the goal. This paper establishes a joint probability scenario to account for the uncertainty of DG and load. An improved harmony search algorithm and an interior point algorithm based on the filtering set are used to solve the model. The analysis results of the example show that the bi-level optimal configuration model of DG conforms to the current state of the power market. The consideration of active management strategies and active management fee achieves mutual benefit and win-win for DG operators and distribution companies, and the model provides a reference for the sustainable development of DG operators.
