The problem of insufficient regulation ability in isolated microgrid operations traditional master–slave control is targeted this research. A hybrid strategy proposed to operate multiple distributed generators (DGs) a with alleviated characteristics. Firstly, virtual synchronous generator adopted the master DG provide voltage and frequency support for system; however, lack participation slave P...

By consulting various worldwide definitions of microgrids and distributed energy, this study presents a microgrid-structured multi-agent system and uses Matlab/Simulink to construct a circuit with microgrid features, which enables the changes in each electrical source and load in the microgrid to be monitored and controlled. This multi-agent system adheres to the Java Agent Development Framewor...

After microgrid transition from the normal operation to the islanded operation the system impedance changes considerably and it affects on the harmonic voltages of the microgrid. In this paper the voltage and current THD before and after islanding are studied with different microgrid configurations. Simulations are also made by applying negative sequence filtering in control system of converter...

The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...

In the upcoming years, an opportunity for a wide range of electricity management solutions arises, thus several researchers have focused their efforts on studying and analyzing various subjects related to the operation of microgrids, smart grids, Vehicle-to-Grid (V2G), responsive demand, among others. On the other side, especially at engineering courses, these topics are primarily covered from ...

Microgrid design entails the selection and sizing of appropriate energy generation and storage technology to meet a known or proposed load profile. For traditional generation technology (i.e. thermal generating plants), it is well known that the incremental costs of meeting high peak demand is much higher than the average cost and hence negatively impacts microgrid economics. On the other hand,...

The pursuit of sustainability motivates microgrids that depend on distributed resources to produce more renewable energies. An efficient operation and planning relies on a holistic framework that takes into account the interdependent decisionmaking of the generators of the existing power grids and the distributed resources of the microgrid in the integrated system. To this end, we use a Stackel...

This paper provides a brief overview of current smartgrid and microgrid technologies and issues associated with their implementation. An architecture of the microgrid for the Department of Electrical Drives and Power Electronics is proposed. Main attention is paid to the control system. The paper sets out the functions and requirements to the main controller for a microgrid control system. The ...

Since the late 1970s, intensive efforts have been made to utilise renewable energy sources, such as wind, hydro, solar and tidal. However, the application of individual distributed generators can cause as many problems as it may solve. A better way to realise the emerging potential of distributed generation is to take a system approach that views generation and associated loads as a subsystem o...
