Influence study of concentrated photovoltaic location on voltage stability (original) (raw)
2015, International Journal of Smart Grid and Clean Energy
Concentrated Photovoltaic modules (CPV) use optics, such as lenses to concentrate a large amount of sunlight onto a small area of solar photovoltaic materials to generate electricity. The solar irradiance level and landscape area are considered as main factors in CPV site on the network. These factors are not sufficient for improving the CPV performance and grid integration .The coupling point of CPV to the grid is an important role and affects the network stability. This paper focuses on the influence study of CPV location on voltage stability .PSS/E has been used as a tool for simulation and validation the integration of CPV to 14-IEEE network as benchmark test. Ac contingency analysis tool is used to study the voltage stability at different cases and locations of CPV. Results indicate that the distributed CPV improves the voltage stability of the network, rather than centralized CPV. Distributed CPV connects at different locations and near to the load. Therefore, the impact of distributed CPV is minimized with respect to voltage stability issue.
