    摘要:

    分布式光伏装机量猛增影响了台区的安全可靠运行,台区储能成为消纳分布式光伏的关键,但台区储能项目投资的经济性与电网可靠性之间难以平衡。对此,提出一种基于台区储能反配新能源模式的综合考虑经济性与可靠性的台区储能优化配置方法。首先,建立台区储能容量优化经济模型;其次,基于台区储能经济性优化结果进行电网可靠性模拟仿真;最后,考虑经济性与可靠性等综合指标,运用优劣解距离法对各节点进行选址评估,通过累积分布曲线确定台区储能配置方案。算例仿真结果表明,文中所提方法可以有效提升配电网分布式光伏消纳能力,更好地平衡了台区储能投资的经济性与电网可靠性,相关结果可为新能源配储比例的合理设置提供借鉴。

    Abstract:

    The capacity of distributed photovoltaic impacts the safe and reliable operation of the distribution network. Energy storage in distribution feeders has emerged as a pivotal solution for consuming distributed photovoltaic. However,it is challenged to balance the economic viability of energy storage investing and grid reliability. In response,a method of optimizing the configuration of energy storage in distribution feeders based on the new model of counter configuration of the renewables from energy storage is proposed,which takes into account both the economy and reliability aspects. Firstly,an economic model for optimizing energy storage in distribution feeders is established. Secondly,a grid reliability simulation is performed based on the results of the economic optimization of energy storage in distribution feeders. Finally,considering the comprehensive indexes of economy and reliability,the different nodes are evaluated for site selection using technique for order preference by similarity to ideal solution (TOPSIS),and the energy storage configuration scheme is determined by the cumulative distribution curve. The simulation results show that the consuming capacity of distributed photovoltaic in the distribution feeders is effectively improved,and better balance the economic viability of energy storage investing with grid reliability,which can be used as a reference for the reasonable determination of ratios of the energy storage for renewables.
