Abstract

Photovoltaic energy is one of the fastest growing renewable energy sources in the worldand as the issue of energy security is becoming more and more important it could be a promising option. But as photovoltaic energy is becoming widespread and penetration level of photovoltaic power plants increase, issues rise in distribution networks.In this paper a power control scheme for a high penetration photovoltaic power plant in a radial distribution network will be presented. This control scheme includes an efficient Maximum Power Point Tracking (MPPT), DC link voltage control by managing power balance between the hysteresis controlled inverter and a boost converter. Another aspect of High Penetration PV (HPPV) which is overvoltage in Point of Common Coupling (PCC) is also investigated and maximum allowable Penetration Level (PL) will be determined. Simulations have been done in Matlab/Simulink environment.

Abstract

Global warming is a direct consequence of consumption of fossil fuels which emit greenhouse gasses as they produce energy. Solar energy is the most available energy throughout the world in which regardless of capital investment is free and most importantly clean and emission free and could be a solution for global warming along with other renewable sources of energy. But as photovoltaic energy is becoming widespread and penetration level of photovoltaic power plants increase, several issues rise in distribution networks. In this paper, a high penetration photovoltaic power plant is designed and issues associated with it are thoroughly discussed. Voltage rise and cloud passage effect are amongst the most challenging issues in design and implementation of a high penetration photovoltaic power plant in distribution networks. Transient effects of cloud passage could lead to unacceptably low voltage in Point of Common Coupling and maximum penetration level must be set according to these issues. An efficient Maximum Power Point Tracking (MPPT) and a DC link voltage control scheme are also presented. Simulations have been done in Matlab/Simulink environment.
