| Abstract | Conventional electric power generating plants are responsible for emitting GHGs like C0₂, NOx and SOx. Therefore, the whole world wants to bring revolution in electric power generating sector by keeping 3E (environmental degradation, energy security and energy sustainability) in mind. Countries around the world are placing considerable faith on renewable energy resources for power generation especially solar, wind, biomass and hydrogen energy. Because, besides being clean, sustainable and secure, these technologies are becoming cheap. Among all, solar is one of the mature technologies and with growing interest on solar photovoltaic generation, its impact on electric power system stability need to be analyzed. Very few work so far has been done on studying the effect on oscillatory and static voltage stability of the electric power system with photovoltaic generator integration. In this research, influence of photovoltaic generation on power system oscillatory and static voltage instability as well as environmental constraints based economical evaluation has been analyzed. The simulation study has been carried out by MATLAB based software, "Power System Analysis Toolbox (PSAT)" and "HOMER". The analysis has been done on IEEE-14 bus and two area test system as well as on real power system (Bangladesh Power System). Photovoltaic generator with out considering the environmental effect on modelling exhibits no effect on oscillatory modes with radiation level change. But, however it adds damping to the system. The system is analyzed with small disturbances (change of penetration, loading level change, distributed resources wide over the area) to see its impact on oscillatory instability. The eigenvalue method is used here to analyze this portion of the research. Continuation power flow is used to analyze the impact of photovoltaic generator on system loading margin. It was found that change of radiation and photovoltaic generator placement has considerable effect on system loadability as well as the size of the generator. Environmental constraints based economical evaluation has been carried out based on real data. And, it was found that relatively higher CO₂ tax is required to make photovoltaic generator competitive with gas, whereas lower CO₂ tax makes it competitive with diesel. |
