分布式光伏发电系统中智能优化器的性能研究
PERFORMANCE STUDY OF INTELLIGENT OPTIMIZER IN DISTRIBUTED PV POWER GENERATION SYSTEMS
摘要
Abstract
This paper investigates the shutdown function,optimization effect,and economic impact of intelligent optimizers in PV power generation systems using a rooftop distributed PV power station as the research object.The results show that:1)the intelligent optimizer can effectively reduce the risk of fire caused by DC arcing only when all PV modules are equipped with intelligent optimizers.2)When PV modules are partially shaded with a shading rate of less than 40%,the intelligent optimizer can mitigate power generation loss by reducing voltage to maintain the output current of the PV modules demonstrating good economic peformance.3)When the consistency of PV modules is good,the benefits of adding an optimizer are insufficient to offset the costs.The economic viability of the intelligent optimizer needs to be comprehensively evaluated based on the actual application scenarios.关键词
