摘要: 在分布式发电市场化环境下,为均衡配电网与分布式光储协同规划时各主体利益,保障规划后各主体的合理效益,提出一种考虑分布式交易机制和不同储能运行策略经济性的规划运行模型。首先,基于代理交易模式,建立考虑光伏预测误差和代理费用的规划层主体利益耦合模型。具体而言,制定考虑光伏预测误差的代理交易结算规则,建立考虑运营商传输成本、网络损耗和合理收益的代理费用模型。其次,建立以各主体投资规划效益为优化目标的双层规划模型;此外,在运行层基于利益耦合模型和储能运行策略得到典型场景下配电网时序运行结果。采用双层改进粒子群算法对所建模型进行求解。以某实际配网为例进行规划求解和分析,比较不同储能运行策略的经济性,分析利益耦合模型的合理性。仿真结果验证了所提方法对保障各主体效益的有效性。

Abstract: In the marketization environment of distributed generation, a planning and operation model was proposed given the distributed transaction mechanisms and the economics of energy storage operation strategies for two main purposes. One is to balance the interests of different subjects in the collaborative planning of the distribution network operator (DNO) and the investor of distributed photovoltaic and energy storage system (PV-ESS), and the other is to ensure the benefits of each subject after the planning. Firstly, the benefit coupling model for the subjects in the planning layer was constructed considering photovoltaic prediction errors and agency costs based on the agency transaction mode. Specifically, the settlement rules of agency transactions were formulated on the basis of photovoltaic prediction errors, and the agency cost model was established considering transmission costs of operators, network loss, and reasonable profit. Secondly, a double-layer planning model was established taking the maximization of the investment and planning benefit of the subjects as the optimization goals. In addition, the timing operation results of the distribution network in typical scenes were obtained in the operation layer using the benefit coupling model and energy storage operation strategy. The double-layer improved particle swarm optimization algorithm was applied to run the model. Taking an actual distribution network as an example for the planning solution and analysis, this paper compared the economics of different energy storage operation strategies and analyzed the rationality of the benefit coupling model. The simulation results verify that the proposed method is effective in ensuring the benefits of different subjects.
