Abstract

Trends in energy generation, as well as consumption, are steadily increasing around the world due to the growing population and remarkable industrialization specifically, the modelling and simulation of photovoltaic (PV) when integration into modern energy networks. The goal of this paper is to study the impact penetration of large scale PV system (LSSPV) when integrated into the modern power grid. In addition, how to avoid the mismatch issue that occurs due to many conditions like as dust, shadows of trees, partially shaded by cloud and some of the nature accident fault such dropping of birds perching. The proposed system consists of PV panels, DC-DC boost converter, hybrid energy storage system with bidirectional DC-DC converter that include the battery and supercapacitor, and inverter to connected with AC grid. The IEEE 9 bus standard system is used to test the proposed model. The effectiveness of the proposed large scale PV system has been validated via simulation Matlab / Simulink. The IEEE 9 bus test system behaviors are studied with or without LSSPV during the steady-state, changes in solar radiation, and during line fault. The simulation results of standard test systems as well as the renewable integrated systems show the compatibility among the commercial and confirm that the LSSPV is suitable for enhancing the voltage profile and improve the reactive power in the grid.
