Advanced Control Architectures for Intelligent Microgrids - Part II: Power Quality, Energy Storage, and AC/DC Microgrids

— This paper summarizes the main problems and solutions of power quality in Microgrids, distributed energy storage systems, and AC/DC hybrid Microgrids. First, power quality enhancement of grid-interactive Microgrids is presented. Then, cooperative control for enhance voltage harmonics and unbalances in Microgrids is reviewed. After, the use of static synchronous compensator (STATCOM) in grid-c...

Advanced Architectures and Control Concepts for MORE MICROGRIDS

Advanced Power Electronic Interface for Hybrid Energy Storage System used for Microgrids

Microgrids are one of the most useful and efficient ways to integrate the renewable energy technologies in order to improve security, quality, reliability and availability of electricity supply. In order to achieve these benefits when a microgrid with a substantial amount of stochastic generation operates in grid connected mode but also during islanding mode, the use of storage systems is essen...

Review of Ship Microgrids: System Architectures, Storage Technologies and Power Quality Aspects

Ship microgrids have recently received increased attention, mainly due to the extensive use of power electronically interfaced loads and sources. Characteristics of these microgrids are similar to islanded terrestrial microgrids, except the presence of highly dynamic large loads, such as propulsion loads. The presence of such loads and sources with power-electronic converter interfaces lead to ...

Distributed Nonlinear Robust Control for Power Flow in Islanded Microgrids

In this paper, a robust local controller has been designed to balance the power for distributed energy resources (DERs) in an islanded microgrid. Three different DER types are considered in this study; photovoltaic systems, battery energy storage systems, and synchronous generators. Since DER dynamics are nonlinear and uncertain, which may destabilize the power system or decrease the performanc...
