Abstract Photo Voltaic power plant is considered as one of the most important renewable energy sources. For different regions and locations, climatic conditions including temperature and solar radiation are continuously changing which make it stochastic in nature. In order to efficiently integrate these PV plants in power grid, intensive analysis should be implemented. Contingency analysis during planning and operation phases guarantees effective integration for PV plant. This thesis proposes a new probabilistic contingency analysis tool to demonstrate the impact of PV plant uncertainty from grid security point of view. For this purpose, a probabilistic model of PV plant is adapted to integrate with contingency analysis algorithm. New severity function for line overloading and bus voltage violation is introduced to consider this uncertainty besides practical system operating limits. Different study cases are discussed. They vary between different scenarios firstly, comparisons of PV plant expansion in different buses simultaneously, second, a comparison between integration PV plant in one bus and distributed capacity between different buses. Finally, conventional generation plant in the original grid is replaced by PV plant at same rated power. |
