Recently, the concept of microgrid (MG) has been developed to assist penetration large numbers distributed energy resources (DERs) into distribution networks. However, integration DERs in form MGs disturbs operating codes traditional Consequently, protection strategies cannot be applied MG against short-circuit faults. This paper presents a novel intelligent strategy (NIPS) for based on empiric...

This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...

This paper analyses the performance of a lowvoltage microgrid, based on microturbines, and presents new control algorithms to improve the efficiency and reliability of microgrids. Due to the importance of islanding and focusing on the efficiency and the harness of the heat of the exhaust gasses in islanded operation mode, a new control algorithm has been developed. Additionally, a new control s...

A shift to a decentralized power generation mainly based on Renewable Energy Sources (RESs) is essential to meet the climate protection goals of reducing greenhouse gas emissions. The fluctuating generation of RESs poses challenges for the stability of the electrical grid. Therefore, energy management systems (EMSs) are essential to cope with the volatility of RESs through an intelligent coordi...

Distributed generation (DG) is one of the key components of the emerging microgrid concept that enables renewable energy integration in a distribution network. In DG unit operation, inverters play a vital role in interfacing energy sources with the grid utility. An effective interfacing can successfully be accomplished by operating inverters with effective control techniques. This paper reviews...

In this article, the smart grid is modeled as a decentralized and hierarchical network, made of three categories of agents: producers, providers and microgrids. To optimize their decisions concerning the energy prices and the traded quantities of energy, the agents need to forecast the energy productions and the demand of the microgrids. The biases resulting from the decentralized learning migh...

Decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. Conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. In this paper, a new droop control s...

A novel power consensus algorithm for DC microgrids is proposed and analyzed. DC microgrids are networks composed of DC sources, loads, and interconnecting lines. They are represented by differential-algebraic equations connected over an undirected weighted graph that models the electrical circuit. A second graph represents the communication network over which the source nodes exchange informat...
