In this paper, a decentralized strategy based on fuzzy logic is proposed for balancing the state of charge of the energy storage units for distributed PV-based active generators. The proposed method, weights the action of conventional droop control loops for privileging the charge of the energy storage unit with the smallest state of charge or force a faster discharge of the energy storage system...
The study of isolated AC microgrid has been under high interest due to the integration of renewable energy resources especially for remote areas, or to improve the local energy reliability. The current trend is oriented to distributed renewable energy sources and their corresponding energy storage system, in order to smooth the variations at the prime energy generator. In this paper, a decentralized...
Coordinated operation of microgrids requires that energy management system takes into account both the available power in renewable energy sources (RES) and storage capacity of energy storage systems (ESS). In this paper, a coordinated architecture of islanded ac microgrids with smooth switching droop control (SSDC) is derived. Based on the proposed SSDC approach, flexible power control of each ESS/RES...
In this paper, a decentralized control for coordinate both active and reactive powers is proposed for islanded microgrids. Compared with the conventional droop control strategies, the proposed control realizes decentralized power distribution among renewable energy sources (RES) and energy storage systems (ESS) according to the local source conditions. Based on bus-signaling method, the ESS is able...
This paper proposes an autonomous active and reactive power distribution strategy that can be applied directly on current control mode (CCM) inverters, being compatible as well with conventional droop-controlled voltage control mode (VCM) converters. In a microgrid, since renewable energy sources (RES) units regulate different active power, the proposed reactive power distribution is adaptively controlled...
