The idea of changing our energy system from a hierarchical design into a set of nearly independent microgrids becomes feasible with the availability of small renewable energy generators. The smart microgrid concept comes with several challenges in research and engineering targeting load balancing, pricing, consumer integration and home automation. In this paper we first provide an overview on t...

Battery energy storage systems (BESSs) have been widely used for microgrid control. Generally, BESS control systems are based on proportional-integral (PI) control techniques with the outer and inner control loops based on PI regulators. Recently, model predictive control (MPC) has attracted attention for application to future energy processing and control systems because it can easily deal wit...

The occurrence of unintentional islanding will seriously threaten the stable operation a microgrid (MG). Therefore, detecting an timely is important premise to ensure operates safely and stably. However, problem dead zone exists in traditional detection process because threshold various electrical feature quantities point common coupling (PCC) cannot be determined effectively. To solve this pro...

DC microgrids have advantages over AC in terms of system efficiency, cost, and size. However, a well-designed overcurrent protection approach for remains challenge. Recognizing this, this paper presents novel differential evolution (DE) based framework microgrids. First, simplified microgrid model is adopted to provide the analytical basis DE algorithm. The does not sacrifice performance criter...

The supply of electrical energy is being increasingly sourced from renewable generation resources. The variability and uncertainty of renewable generation, compared to a dispatchable plant, is a significant dissimilarity of concern to the traditionally reliable and robust distribution systems. In order to reach the optimal operation of community Microgrids (MGs) including various Distributed En...
