A Review on Reactive Power Compensation of Distributed Energy System

Reactive power, an expression of significant importance in power sector is always infected with a situation of imbalance caused due to rapid changes in load in the system. Variation in reactive power gives direct impact on voltage levels, frequency and finally to system stability. In distributed energy generation (DEG) system, major sources of power are designed to give DC output, but most loads are AC. So almost in all cases, a battery - inverter system is implemented to synchronize the DEG with load or AC grid. In such systems, reactive power needs are satisfied using generic systems as well as special systems. In this study, we will glance through major available systems and will try to round up to the best possible solution available.
