Investigation of Critical Time Analysis Considering Shunt Compensation Interconnecting WECC SPV Model

Increasing demand for renewable energy (RE) in the electric power system contributes to the consumption of fossil fuels. However, massive penetration of these systems m introduces challenges in achieving power system stability. Modelling the RE in commercially available power system simulation is an essential stability study. In the past decade, renewable energy, such as the solar PV (SPV) model, has been in high demand in both industrial and research academic sectors. In this paper, the Renewable Energy Modeling generic model of the Western Electricity Coordinating Council (WECC) model is used to analyze the behaviour of dynamic representation in electrical performance interfacing to 39 bus networks. The power flow analysis of the network characteristics, including lines, bus bars, and transformers, is constructed using a Power System Simulation for Engineering (PSSE) simulation tool. The uniqueness of this paper presents an investigation of shunt position based on improved over-voltage limit and stability strength analysis. The performance of this integration model has generated 900 seconds time frame, and the irradiation of PV is assumed to be constant. The results indicate that the new network design and methodology successfully determine the number of shunt capacitors that should be installed in this distribution network under stable conditions and installing more than two capacitors also contribute to significant losses in the network. The performance indicator also has been presented at the end of this paper. The simulation findings reveal the critical fault time when SPV is involved; nevertheless, when the number of shunts is increased, the loss will grow proportionally.
