INTEGRATION OF SOLAR ENERGY INTO NATIONAL ELECTRIC GRI

Abstract

Renewable energy represents one of the options to replace the fossil fuel. Photovoltaic represents one of the techniques used for converting solar energy into electrical energy. The Photovoltaic system is installed either as stand-alone or connected to network via power electronic converter. The main issues for solar power integration are unit sizing and negative impact mitigation of solar power in the system. The injected solar energy may affect the frequency and voltage of the system. Power storage can be used to facilitate frequency control during solar power integration as seen in this thesis when BESS is connected in the system the frequency is kept within the permissible limit (49.5-50.5Hz) although the significant change in solar power injection.
