市场环境下,随着分布式电源(DG)的广泛接入,DG 运营商成为配电网中新增的利益主体。当 DG 运营商在进行 DG 规划时,如何根据配电公司可能的投资行为采取最优的决策方案是目前亟须解决的重要问题。针对该问题,提出了一个考虑 DG 运营商和配电公司不同利益需求的双层规划模型,该模型的上层为 DG 运营商的 DG 选址定容规划,下层是对配电公司无功电容器选址定容规划和购电策略制定的预测,并研究了 DG 规划与无功电容器规划之间的相互关系。此外,文中还提出了主动管理费用(AMF)的概念,并分析了其对 DG 和无功电容器的规划结果以及各个利益主体的目标所产生的影响。通过 Levy 飞行杜鹃搜索(LFCS)算法对上述模型进行求解计算,算例分析结果表明所述模型可以反映双方的利益博弈关系,合理制定 AMF 可以促进 DG 的消纳。

Distributed generator (DG) companies have become new stakeholders in a distribution network with widespread access of DG in the electricity market environment.During DG planning,it is an important problem demanding prompt solution for a DG company to make appropriate decisions according to its probable investment behavior.Thus,a bi-level programming model is presented that considers the different interests of the DG company and the distribution company.The model consists of an upper level for siting and sizing of DG,and a lower level for forecasts of siting and sizing of capacitors and the strategy for purchasing power.Then the relationship between DG planning and reactive capacitor planning is studied.In addition,the concept of active management fees (AMFs) is proposed,whose effects on the planning of DG and reactive capacitor and the objective of every stakeholder are analyzed.Levy flight cuckoo search(LFCS) algorithm is used to solve the above model.Numerical results show that the proposed model is able to reflect the game relationship between the two parties, and rational AMFs can promote the accommodation of DG.
