Conventional centralized and distributed structures for secondary frequency control (SFC) in an islanded microgrid rely on communications. However, this may degrade the reliability of the system if communication delays or failures occur. As a potenti

Energy storage systems are an effective solution to manage the intermittency of renewable energies, balance supply, and demand. Numerous studies recommend adopting a shared energy storage system (ESS) as opposed to multiple single ESSs because of the

The concept of a virtual power plant (VPP) was introduced for supporting market participation of small-scale renewable energy-based generators (REGs). In a VPP, energy storage systems (ESSs) and micro-turbine-based generators (MTGs) are used together
