基于灵活性提升的电力系统储能装置定容方法
|
摘要
为更好地解决可再生能源并网问题,针对系统应对短时不确定性的响应能力,定义电力系统灵活性及其评估指标,并基于此提出一种储能优化配置方法。分析电源侧的不确定性,定义电力系统灵活性,针对可再生能源出力不确定性,定义电源灵活性评估指标。从选址和定容的角度,阐述储能配置的原理和方法,并基于电源灵活性评价,综合考虑系统灵活性需求和新建储能成本,建立储能配置模型并求解。以IEEE-118节点测试系统验证方法的有效性。
To solve the problem of renewable energy access and aiming at system's response capability to short-term uncertainty, power system flexibility and its evaluation index are defined. A method of energy storage configuration based on flexibility evaluation is proposed. The uncertainty from power supply is analyzed. Aiming at the uncertainty of renewable energy, a source flexibility evaluation index is defined. The principle and method of energy storage configuration are presented from the aspect of siting and sizing. The energy storage configuration model is created and solved considering both the system flexibility requirements and energy storage costs based on the evaluation of power flexibility. Finally, case study on IEEE 118-bus test system shows that the proposed method is effective.
