为解决微网功率波动、谐波等问题,提出了利用混合储能技术平抑功率波动,同时补偿谐波、无功和不平衡电流的多目标控制策略。此外,基于瞬时功率理论和谐波电流检测算法,实现了多目标并网参考电流的计算方法。控制储能装置实时补偿微网公共连接点电能质量,实现电能质量综合治理。算例结果验证了该方法的有效性。
In order to solve the problems of power fluctuation and harmonics in microgrids, a multi-objective control strategy is proposed to stabilize power fluctuations and compensate harmonics, reactive power and unbalanced currents with hybrid energy storage technology. In addition, based on the instantaneous power theory and harmonic current detection algorithm, a multi-target grid-connected reference current calculation method is achieved. Control energy storage device real-time compensation for micro-grid public connection point power quality, to achieve comprehensive management of power quality. The result of the example verifies the validity of the method.
