This paper explores the structure, use, and value of Distributed Grid Management as a process and technology to support distributed grid optimization functions and microgrids to better integrate into the electrical grid small quantities of local, distributed power generated from renewable resources. The paper describes the value of distributed distribution management as it applies to Microgrids...

Integration of demand response (DR) programs and battery energy storage system (BESS) in microgrids are beneficial for both microgrid owners and consumers. The intensity of DR programs and BESS size can alter the operation of microgrids. Meanwhile, the optimal size for BESS units is linked with the uncertainties associated with renewable energy sources and load variations. Similarly, the partic...

This paper presents a mathematical model of frequency control in isolated microgrids, which is integrated into the Unit Commitment (UC) problem. In conventional UC formulations, power outputs are considered fixed between two periods, yielding a staircase pattern with respect to the energy balance of the generation and demand for a typical dispatch time horizon (e.g., 24 h). However, in practice...

In this paper a new method is introduced to increase the resiliency of a distribution grid by forming robust microgrids after extreme contingencies following disasters. The method tries to serve as much load as possible by forming microgrids with alleviated vulnerability based on the Manchester model and optimal AC power flow. The main feature of the proposed method is that the formed microgrid...

One of the most important requirements of microgrid operation is to maintain a constant frequency such as 50 Hz or 60 Hz, which is closely related to a power balance between supply and demand. In general, microgrids are connected to power grids and surplus/shortage power of microgrids is traded with power grids. Since islanded microgrids are isolated from any power grids, the decrease in genera...

This paper proposes a distributed multi-agent system (MAS) framework for market-based control in Microgrids. The proposed system consists of two main entities, Energy Selling Agents (ESAs) and Energy Buying Agents (EBAs). In order to alleviate the internal complexity of the agent, three kinds of delegate mobile agents are designed. They are issued by the corresponding agents according to their ...

Smart grid has integrated an increasing number of distributed energy resources to improve efficiency and flexibility of power generation and consumption as well as the resilience of the power grid. The energy consumers on the power grid (e.g., households) equipped with distributed energy resources can be considered as “microgrids” that both generate and consume electricity. To facilitate energy...

The growing proliferation of microgrids and distributed energy resources in distribution networks has resulted in the development of Distribution Market Operator (DMO). This new entity will facilitate the management of the distributed resources and their interactions with upstream network and the wholesale market. At the same time, DMOs can tap into the flexibility potential of these distribute...

Abstract: Interest in DC microgrids is rapidly increasing along with the improvement of DC power technology because of its advantages. To support the integration process of DC microgrids with the existing AC utility grids, the form of hybrid AC/DC microgrids is considered for higher power conversion efficiency, lower component cost and better power quality. In the system, AC and DC portions are...

This paper proposes a distributed algorithm for online energy management in networked microgrids with a high penetration of distributed energy resources (DERs). The implementation of networked microgrids with high penetration of DERs brings power generation closer to electricity users, which has advantages of increasing power supply efficiency and reliability by shortening the power supply deli...
