Abstract:
Currently, there is a significant increase in the development and operation of the Renewable Energy Sources all-around the world due to the increasing environment uncertainties. PV and Wind are the most capable alternative sources to the conventional energy sources. These sources are rapid operational and easily integrated into the power system over the last few decades and are predictable in the development of the further upcoming decades. with concerning to the PV and Wind energy sources in the power system is the instability and irregularity, which create the protection problem in the power system reliability. Such energy sources depending upon various factors in the power system reliability. The size and site of the RES, the penetration of intermittent RES in the power system, the point common coupling in the grid-connected network, the relationship between the availability of multiple sites and the relationship among load and RES. Such factors are considered in the analysis of the power system reliability and impact of reliability on the Hybrid PV-Wind. In addition to the economic benefit of the supply power to the consumers. To addresses such challenges, this thesis first analyzed the technical performance indices, in an attempt to harness the maximum possible benefit. These indices are attempting to quantify some operational impacts for long-term planning tool in the evaluating the renewable energy penetration in transmission networks. The CIGRE Medium-voltage Benchmark Model is used as a test system throughout this thesis to analyze the factor affecting the adequacy analysis. generally, the analysis of the RES integration in the power system acquiring the stochastic nature of the load and RES to satisfactory the RES penetration level in the system. For such purpose, the probabilistic method is implemented. The modeling and simulation are performed by powerful grid simulator DIgSILENT Power Factory. Which qualifies for fast and reliable performance of a wide range of calculating procedures.
