摘要:
针对利用频率变化率和等效转动惯量求取功率缺额存在精确性较差的问题,提出了一种改进的微电网功率缺额求取方法. 根据微电网频率变化率和近似等效转动惯量求出第一次负荷切除量,再利用微电网的频率变化信息进行第二次切负荷,通过两次切负荷以保证微电网的安全、稳定运行. 仿真结果表明,改进后的方法在求取有功缺额时不依赖微电网等效转动惯量的准确参数,具有更好的优越性、准确性和快速性.
Abstract:
Aiming at the inaccuracy caused by power shortage method using frequency change rate and equivalent moment of inertia,the paper proposes an improved algorithm to enhance accuracy of the power shortage of microgrid. To begin with,the load capacity to be curtailed for the first time is calculated according to the frequency change rate and the approximate equivalent moment of inertia of microgird. And then,the second load curtailment is conducted in line with the frequency change information from the microgrid after the first time. As a result,safe and stable microgrid operation can be achieved by two times of load curtailment. Simulation results show that the improved algorithm can calculate the power shortage without depending on the accurate parameters of equivalent moment of inertia of microgrid, and that it is more superior, accurate and rapid.
