DYNAMIC PERFORMANCE MODEL OF HYBRID POWER PLANT (WGS + GAS TURBINE)

It is known that the role and importance of energy storage increases when operating a power plant based on a renewable energy source. This feature of the power plant operation is associated with the unevenness of electricity generation due to natural conditions. The paper assesses the performance of a hybrid power plant, namely, the degree of mutual influence is determined when operating a wind power plant and a gas turbine in a single system. The gas turbine is considered as a backup energy source, which is switched on in the absence of wind. Problems arising during the operation of a hybrid energy system consisting of wind power plants (WPP) and a thermal power plant (GTU) arise mainly due to the natural unpredictability of the wind power plants. A dynamic wind turbine model coupled with a power system model is needed to develop options for optimizing its performance in terms of efficiency, fuel consumption, and CO2 emissions. The results illustrate the significant impact that dynamic performance modeling has on the design of a hybrid power system optimization and control system.
