基于模糊逻辑控制的光储直柔双极系统不平衡电压抑制策略
Unbalanced Voltage Suppression Strategy of PEDF Bipolar System Based on Fuzzy Logic Control Method
摘要
Abstract
Parameter variations in the photovoltaic,energy storage,direct current,and flexibility(PEPF)bipolar system will lead to unbalanced voltages between the positive and negative busbars,increasing network losses while threatening system stability.To ad-dress this,an imbalance voltage suppression strategy based on fuzzy logic control is proposed.Firstly,the impact of system parameters on inter-pole voltage imbalance is analyzed based on the structure of the photovoltaic storage direct-flexible bipolar system and current balance equations.Then,a fuzzy logic controller is employed to adjust the droop control parameters of each power source converter by collecting data on positive/negative busbar voltages and system voltage imbalance.This process modifies the output voltage and power of each power source converter,ultimately suppressing the inter-pole voltage imbalance of the photovoltaic storage direct-flexible bipolar system within an acceptable range.Simulation tests on the photovoltaic storage direct-flexible bipolar system model validate the effectiveness of the proposed method.关键词
