The large deviation in wind speed and irregular solar radiation causes extreme fluctuations of output power in offshore wind farms and photovoltaic system respectively. In this perspective to minimize the deviation in frequency and bus voltages, One of the most simple and suitable options is to interconnect a DGS with conventional generation resources in the power system, However, in such hybrid Power systems (HPS), changes in the load demand and wind power variation disturb the frequency and bus voltages. This paper purposes for the integration of different distributed energy resources (DER) like offshore wind, stand-alone PV system, Industrial diesel engine generator (IDEG), Polymer electrolyte membrane fuel cells (PEMFC) with energy storage elements like battery energy storage system (BESS), flywheel energy storage system (FESS), ultracapacitor (UC), along with LFC-Heffron-Philips model (HPM) as conventional generation resources. All the models are simulated using MATLAB/SIMULINK, a relative and graphical assessment of frequency deviation and bus voltages for different hybrid power systems is also carried out in the presence of high-voltage alternating current (HVAC) line and high-voltage direct current (HVDC) link. Thus further aims for Analytical analysis and modeling of optimized hybrid power system to enhance power system stability. Analytical analysis reflects the enhancements in frequency and bus voltages deviation profiles with use of LFC-Heffron Philips model of a single-machine infinite bus (SMIB) system, also graphical and quantitative analysis of square integral error (S.I.E).
