Research Paper from the year 2014 in the subject Energy Sciences, grade: B.E EEE First Class, , course: M.E Power & Energy Systems Engineering, language: English, abstract: In the proposed paper, it is described how a Solar PV Farm along with a battery storage system can be used to regulate grid voltage in a PV-Wind integrated distributed generation System. At night time Solar PV system is normally dormant (i.e. it does not generate power) but the stored power in batteries can be utilised efficiently to regulate the common coupling voltage by means of a FACTS based Static Synchronous Compensator (STATCOM) thereby improving the power quality. Various Utilities are facing major issues with Grid Integration of various types of Renewable Energy Distributed Systems while ensuring power quality , Regulation and Stability. During day time the inverter of PV system provides the power to Grid but during night time PV farm is inactive and stored energy in the batteries can be used as power source to PV inverter for implementing a STATCOM. with advancements in RES and increasing DG systems to provide for load demand the quality of power has to be maintained to optimum value and this paper focuses purely on improving regulation of voltage without using external regulation devices but the installed RES system. In order to implement and validate the concept of the prescribed paper SIMULINK Tool has been used.
