Optimization And Stability Analysis Of Offshore Hybrid Renewable Energy Systems

Abstract

Many countries have executed Offshore wind farms to Compensate electricity shortage. Offshore wind energy have a larger capacity factor than onshore wind energy. An offshore wind energy could competitive with conventional power plants because it could have a larger amount of MWs. The intermittent nature of offshore wind farms could have significantly impact on the operation and maintenance cost, stability, and reliability of it’s connected power grid. To overcome the intermittency nature off wind energy and ensure the stability of the system during large events, modern offshore hybrid solar and wind farms have implemented. The effects of a large-scale offshore hybrid farm (OHF) on power system stability are studied. The high voltage direct current is the optimal system to connect the offshore hybrid farm to the main grid through a voltage source converter (VSC) because the large distance to shore. The proposed model is studied on the IEEE New-England 10-machine 39-bus test system. Modeling and stability analysis the hybrid offshore hybrid farm are presented. In this paper, a developed method is proposed for optimal sizing of the offshore PV/wind hybrid system taking into account the dynamic stability of power grid. The simulation model is created using Digsilent power factory.
