TLDR
Depending on the type and depth of penetration of distributed energy resource units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems.Abstract:
The environmental and economical benefits of the microgrid and consequently its acceptability and degree of proliferation in the utility power industry, are primarily determined by the envisioned controller capabilities and the operational features. Depending on the type and depth of penetration of distributed energy resource (DER) units, load characteristics and power quality constraints, and market participation strategies, the required control and operational strategies of a microgrid can be significantly, and even conceptually, different than those of the conventional power systems.read more

Power Sharing Between Microgrids Based on a Secondary Market
TL;DR: A multiple-biding policy, where the users can adjust the future bids based on the past transaction, which can improve the satisfactory degree when the utility by consuming the power is bigger, is proposed.
Hierarchical Control of Inverter-Based Microgrids
TL;DR: A polynomial time optimal power flow (OPF) solver which finds an optimal operating point for the inverters of the distributed energy resources and a novel distributed controller that addresses the control challenges originated from limited generation, mixed R/X ratio lines, and lack of power inertia properties of islanded microgrids are proposed.
