The increasing energy demands are stressing the generation and transmission capabilities of the power system. Distributed generation (DG), which generally located in distribution systems, has the ability to meet some of the growing energy demands. However, unplanned application of individual distributed generators might cause other technical problems. The Microgrid concept has the potential to ...

The evolution of smart microgrid and its demandresponse characteristics not only will change the paradigms of the century-old electric grid but also will shape the electricity market. In this new market scenario, once always energy consumers, now may act as sellers due to the excess of energy generated from newly deployed distributed generators (DG). The smart microgrid will use the existing el...

In this paper an analytical approach is conducted to evaluate the droop control method in an islanding microgrid. Droop control is the key solution for sharing the demand power between generators in autonomous microgrids where there is no support from the electricity distribution grid. In the paper, three important load types are investigated to verify the droop control performance. First, coup...

Abstract The purpose of this paper is to study how to apply distributed storage into a photovoltaic microgrid for rural villages with electrical network powered by renewable sources and small thermal generators. Using distributed storage helps to reduce Joule losses and voltage drops. This allows reducing the cable’s section or the power source’s size. The main work will focus on optimizing the...

Present power systems face problems such as rising energy charges and greenhouse gas (GHG) releases. These may be assuaged by participating distributed generators (DGs) demand response (DR) policies in the distribution system (DS). The main focus of this paper is to propose an management (EMS) approach for campus microgrid (µG). For purpose, a Pakistani university has been investigated optimal ...

This paper proposes two control strategies for the islanding operation of hybrid microgrid with a high penetration of wind driven cage induction generators. The control strategies combine approaches traditionally applied to self-excited cage induction generators with recent approaches for microgrid’s islanding operation. The proposed control strategies aim to facilitate the higher integration o...

In this article, the energy market is a modeled as a Stackelberg game involving three categories of agents: microgrids made of end users sharing the same energy provider, suppliers and generators. The energy production is decentralized involving non-renewables, renewables and demand response performed at the microgrid level. We compute analytically the Nash equilibrium of the game in the genera...

Objectives: This study proposes a droop controlled voltage unbalance reimbursement technique in an islanded microgrid. Methods/Analysis: The control system is executed in áâ static reference frame work. Here the distributed generators (DGs) inverters are managed appropriately to compensate imbalance in allocating active as well as reactive powers. The control system includes active as well as r...

Application of individual distributed generators can cause as many problems as it may solve. A better way to realize the emerging potential of distributed generation is to take a system approach which views generation and associated loads as a subsystem or a “microgrid”. During disturbances, the generation and corresponding loads can separate from the distribution system to isolate the microgri...
