Abstract
The high penetration rate of renewable energy resources (RESs), especially, in the form of photovoltaics (PVs) and wind turbines (WTs) has made the simulation and analysis of power systems more complex because of increased nonlinearities and uncertainties. Accordingly, electromagnetic (EMT) and phasor models have been developed well as common modeling approaches for considering characteristics of RESs into power system studies. This paper develops a simplified model to represent the characteristics of PVs and WTs in phasor domain simulation. The proposed model reduces the three-phase model of PVs and WTs to a circuit with two controlled current sources and considers the control and protection systems of these resources as well as environmental conditions effects on their output power. Simulation results and comparison study cases validate the correctness of the proposed model.
