| Abstract: |
| With rapidly growing of Renewable Energy Sources (RESs) in renewable power systems, several disturbances
influence on the power systems such as; lack of system inertia that results from replacing the synchronous
generators with RESs and frequency/voltage fluctuations that resulting from the intermittent nature of the RESs.
Hence, the modern power systems become more susceptible to the system instability than conventional power
systems. Therefore, in this study, a new application of Superconducting Magnetic Energy Storage (SMES) (i.e.,
auxiliary Load Frequency Control (LFC)) has been integrated with the secondary frequency control (i.e., LFC) for
frequency stability enhancement of the Egyptian Power System (EPS) due to high RESs penetration. Where, the
coordinated control strategy is based on the PI controller that is optimally designed by the Particle Swarm
Optimization (PSO) algorithm to minimize the frequency deviations of the EPS. The EPS includes both
conventional generation units (i.e., non-reheat, reheat and hydraulic power plants) with inherent nonlinearities,
and RESs (i.e., wind and solar energy). System modelling and simulation results are carried out using Matlab/
Simulink® software. The simulation results reveal the robustness of the proposed coordinated control strategy
to preserve the system stability of the EPS with high penetration of RESs for different contingencies. |
