基于目标机会约束规划的储能容量优化配置模型

针对高比例可再生能源的不确定性给主动配电网的电力平衡与灵活性运行带来的影响,提出了一种基于目标机会约束规划的储能容量配置方法。首先分析了含高比例可再生能源的主动配电网中典型"鸭型净负荷曲线"场景下的电力需求与灵活性需求问题,由此引入目标机会约束规划方法,建立了考虑电力需求裕度、灵活性需求裕度的目标机会约束规划模型以配置储能资源。最后,通过算例验证所提模型的有效性,仿真结果表明,所提储能容量优化配置模型及其协同运行方案能有效解决高比例可再生能源接入下典型"鸭型净负荷曲线"场景中的电力需求以及灵活性需求不足问题。

An Optimal Allocation Model of Energy Storage Capacity Based on Goal-Chance Constrained Programming

Considering the impact of high renewable energy penetration on the power and energy balance and flexible operation demands of active distribution network, this paper proposes a capacity allocation method of energy storage based on goal-chance constrained programming.Firstly, we analyze the power demand and flexibility demand problems of active distribution network with high penetration of renewable energy under the typical 'duck type net load curve' scenario.To deal with that, we propose a goal-chance constrained programming method for the optimal allocation of energy storage resources, which aims optimize the balance of power demand margin and flexibility demand margin.Finally, we verify the effectiveness of the proposed model through the test cases.The simulation results show that the proposed energy storage capacity allocation model and its coordinated operation scheme can effectively achieve the power balance demand and flexible goals in the typical 'duck type net load curve' scenario with high penetration of renewable energy integration.
