Power Quality Improvement in Grid Connected Battery Storage Energy Source at Distribution Level
Today, increase the demand of electrical energy at various level i.e. industrial, home appliance, irrigation etc. Electrical energy limited because total energy requirement is supplied by the burning of fossil fuels and it is limited. In this paper, the authors present a control strategy of three phase four wire grid interfacing inverter to effectively utilize the battery storage energy at distribution level. Controlling of inverter in such a way that to utilize the following function compensate load current (i.e. reduce harmonics), compensate load voltage (i.e. reduce harmonics), compensate load reactive power and load neutral current and improve power quality at load side.
