Coordination and performance analysis of pumped hydro storage system integrated with solar, wind hybrid system

Power generation and energy needs of consumers will always be uneven; there exists a mismatch between two terms. Renewable energy sources are widely and increasingly applied in the electrical power generation. Connecting these sources to the power network improves flexibility, reliability, security, efficiency and it releases substations from some constraints. With the increasing penetration of solar and wind power into electric power grid, to match the demand requirement a dynamically stable energy storage system is required which can response to the system with in less time as well as can make the overall system more stable. Energy storage can be used to mitigate the problems associated with the fluctuating output power of the Wind turbines and Solar PV arrays due to changing wind speed and solar irradiation intensity. Using renewable generation in combination with storage systems is one way to tackle voltage and frequency regulation issues. Pumped Hydro Storage Systems are more stable, help in making Grid more stable and safe from different types of disturbances. This paper deals with coordination and performance analysis of Hybrid system consists of solar, wind and Pumped Hydro Storage Systems (PHSS).
