Ultracapacitors (UCs), with their features of high power density and high current charge-discharge, have become the best choice for dynamic power compensation to improve the stability of microgrids and are increasingly being applied in microgrids. This paper presents the control of an energy storage system (ESS) based on ultracapacitors in the context of grid-connected microgrids. The ESS is co...

Microgrids are increasingly being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. However, the technical challenges associated with the operation and controls are immense. Management of dynamic power balances, power flow, and network voltage profiles imposes unique challenges in the context of microgrids. Stability of t...

Dealing with multi-objective problems has several interesting benefits, one of which is that it supplies the decision-maker complete information regarding Pareto front, as well a clear overview various trade-offs are involved in problem. The selection such representative set is, and itself, problem must take into consideration number choices to show uniformity representation and/or coverage ord...

This paper presents a model for reliability evaluation of Microgrids with Distributed Generation based on renewable energy resources. In this approach, DG participates in the network operation coordination as an active agent and not as a decentralized generation under which the utility has no control. Stochastic models are considered for representing generation availability related to wind ener...

There are numerous opportunities and challenges in integrating multiple energy sources, for example, electrical, heat, electrified transportation. The operation of multi-energy sources needs to be coordinated optimized achieve maximum benefits reliability. To address the thermal, transportation electrification demands a sustainable environmentally friendly microgrid, this paper presents mixed i...

Multi-inverter microgrid systems, particularly those with loop topology, offer higher power supply reliability and robustness compared to conventional radial distribution systems. In meshed communication-less protection schemes have proved be ineffective for multi-inverter microgrids due bidirectional flow, limited controlled fault currents generated by the voltage source converters interfacing...
