Abstract
Replacement of conventional generation units with a large number of renewable energy sources RESs causes an undesirable influence to the Egyptian power system EPS frequency stability, excessive supply due to full DGs generation due to the lack of system rotating inertia. The EPS consists of several conventional generation units (i.e., non-reheating, reheating, and hydraulic power plants) with inherent nonlinearities, and RESs (i.e., solar and wind energy). In order to solve this challenge, this paper provides a tertiary modified virtual inertia control loop-based energy storage system ESS as an active solution to improve the EPS stability during contingencies, and diminish the frequency deviations and regulate the power flow. In this method, the ability to imitate damping and inertia properties are presented based on the derivative technique. A comparative study between the conventional EPS with/without virtual (inertia + damping) is also presented. The constructed results using Matlab/Simulink software show the superior effectiveness and control effect of the proposed control method in terms of accurate tracking of the reference frequency and attenuating noise over the traditional one. Finally, it was verified that the auxiliary enhanced virtual inertia mechanism assisted the EPS by suppling further power inertia to robust the frequency against RESs and load demand penetrations.
