This paper focuses on proposing a multi agent system to control distributed in a microgrid aimed at intentional islanding and Load-Shedding. The multi agent system consists of three main agents such as Control, DER (Distribution Energy Resource) and Load agent. Each agent serves the different responsibility that will discuss in this paper. The proposed multi agent based control architecture is ...

Microgrids comprise low voltage distribution systems with distributed energy resources (DER) and controllable loads which can operate connected to the medium voltage grid or islanded in a controlled coordinated way. This concept aims to move from “connect and forget” philosophy towards an integration of DER. Microgrids are expected to provide environmental and economic benefits for endcustomers...

The paper highlights on a new method to solve the network reconfiguration problem. The uncertainty of system loads vary from time to time and makes the distribution system operation and control more complex. Thus for a feeder system power loss is not at its minimum. In this context a methodology to reconfigure the microgrid and also to facilitate its operation in autonomous mode is being discus...

This paper presents modeling and control of a microgrid based on hybrid renewable energy sources including Photovoltaic (PV), Fuel Cell (FC) and Battery Energy Storage (BES). The overall configuration of the microgrid including dynamic models of PV, FC, BES and its power electronic interfacing are briefly described. Then controllers design methodologies for power electronic converters in order ...

The foremost issues of 21 century are challenging demand of electrical energy and to control the emission of Green House Gases (GHG) emissions. Renewable energy resources based sustainable microgrid emerges as one of the best feasible solution for future energy demand while considering zero carbon emission, fossil fuel independency, and enhanced reliability. In this paper, optimization and impl...

his investigation tried to control a standalone hybrid DC microgrid in islanded operation mode by using decentralized power management strategies. Unlike common approaches where a Photovoltaic (PV) module is controlled as current source, the proposed strategy controls PV arrays as a voltage source that follows the current/voltage adaptive characteristic curve. Proposed I/V characteristic for hy...

A set of power generators and loads is considered a microgrid if, in comparison to larger power systems, they are smaller and have lower ratings and capacities. An islanded microgrid is a microgrid that is not connected to a larger power system. Generally, ac power systems have three main objections. First, they must always balance power generation with demand. Secondly, they must regulate freq...

Residential microgrid has the capability to participate in the distribution grid as a very flexible and dynamic component for demand side energy management (energy efficiency, peak-load reduction, and demand response). Various hierarchical (appliance, home, and neighborhood level) advanced control algorithms need to be developed and validated for such residential microgrids. GridLAB-D is the mo...

Voltage source inverters (VSIs) are usually used for all kinds of distributed generation interfaces in a microgrid. It’s the microgrid’s superiority to power the local loads continuously when the utility fails. When in islanded mode the voltage and frequency of the microgrid are determined by the VSIs, therefore the power quality can be deteriorated under unbalanced and nonlinear loads. A volta...
