High penetration of renewable energy sources into isolated microgrids (µGs) is considered a critical challenge, as µGs’ operation at low inertia results in frequency stability problems. To solve this virtual control based on an storage system applied to enhance the and damping properties µG. On other hand, utilization phase-locked loop (PLL) indispensable for measuring frequency; however, its d...

In power electronics-dominant systems (PEDSs), the declining-inertia issue is one of most significant challenges to tackle. The inertia emulation from DC-link capacitors cost-effective and application-friendly solution enhance system inertia. Although virtual control capacitor supports grid frequency with a relatively long-term effect, it affects dynamic converter at multiple timescales. turn, ...

The Photovoltaic (PV) plants are significantly different from the conventional synchronous generators in terms of physical and electrical characteristics, as it connects to the power grid through the voltage-source converters. High penetration PV in power system will bring several critical challenges to the safe operation of power grid including transient stability. To address this problem, the...

The distributed control of a microgrid is fully dependent on advanced information and communication technologies that are sensitive to cyber-physical systems. Cyberattacks, such as denial-of-service (DoS) attacks, can cause unstable operation low-inertia microgrids. This paper proposes enhanced virtual inertia under DoS attacks using an improved resilient model predictive (IRMPC)-based energy s...

Since modern power systems are susceptible to undesirable frequency oscillations caused by uncertainties in renewable energy sources (RESs) and loads, load control (LFC) has a crucial role get these systems’ stability back. However, existing LFC techniques may not be sufficient confront the key challenge arising from low-inertia issue, which is due integration of high-penetration RESs. Therefor...

In the microgrid, virtual synchronous generator technology can significantly enhance anti-interference characteristics of system frequency and bus voltage, as well solve problems insufficient damping low inertia. However, active power oscillation caused by fluctuations grid faults threaten stable operation seriously. Therefore, for an alternating current (AC) microgrid multi-virtual (VSG) paral...

Single widespread employment of renewable energy sources (RESs) contributes to the shortage in inertia microgrid (MG). After this, frequency stability may regress as a result power imbalance or minor load fluctuations. This paper proposes an explicit adaptive modified virtual control (VIC) based on online Archimedes optimization algorithm (AOA) identifier for MG containing thermal, wind, and so...
