摘要
间歇式新能源发电的大规模接入使电压越限问题时有发生,而储能电站可与新能源场站协调配合来实现无功电压调节。提出一种储能与清洁能源无功电压协调控制策略。首先分析了储能和新能源场站对电网进行无功电压调节的原理;其次提出了联合系统无功输出功率的计算方法;之后通过双层分配策略,实现储能和新能源场站无功功率的合理分配;最后以湖南某区域电网作为测试算例验证了所提出的方法的有效性。
The large-scale access of intermittent new energy power generation induces moderate occurrence of over-voltage,and energy storage stations can coordinate with new energy generations to achieve reactive voltage regulation.This paper proposes a coordinated control strategy of reactive voltage between energy storage and clean energy generation.Firstly,the principle of reactive voltage regulation of power grid by energy storage stations and new energy sources is analyzed.Secondly,calculation method of reactive power of the joint system is proposed.After that,the bilayer allocation strategy is used to achieve proper allocation of reactive power between energy storage stations and new energy sources.Finally,a regional power grid in Hunan is used as an exemplary test case to verify the effectiveness of the proposed method.
