Secondary Frequency Control of a Multi-area Power System Integrated with Plug-in Electric Vehicles and Renewable Energy Sources

摘要

The integration of plug-in electric vehicles (PEVs) has a number of benefits, due to which the number of PEVs integration to the power system is likely to rise. One major benefit of PEVs integration is their contribution in the frequency regulation of the system under load fluctuations. This paper presents an aggregate model of a power system with the integration of renewable energy sources (RES) and PEVs. For the purpose of secondary frequency control, Wind Driven Optimized two degree of freedom Proportional-Integral-Derivative (2DOF-PID) controller is applied. The impact of integrating RES and PEVs to the multi-area interconnected power system has been studied vigorously under nominal system conditions in this paper. It is found out from the studies that PEVs play a very vital role in frequency regulation. Also, the effect of PEVs and RES has been studied under random loading conditions, and it is revealed that the impact is very effective.
