“…When the micro-grid is operates in island mode, the crucial situation is an energy balance between supply and demand because the load is dominantly supplied by the local sources. If there are any imbalance in the network, the system can lead to significant frequency deviations [5][6][7][8]. Many research work related to the micro-grid power system frequency study with variety of motivation has been done and most of them involved the large system network with multiple generators and multi area.…”

A micro-grid is a part of power system which able to operates in grid or islanding mode. The most important variable that able to give us information about the stability in islanded micro-grid network is the frequency dynamical responses. The frequency analysis for multi-area micro-grid network model may involve a complicated of mathematical equations. This makes the researcher intending to omit several unnecessary parameters in order to simplify the equations. The purpose of this paper is to show an approach to derive the mathematical equations to represent the average behavior of frequency dynamical responses for two different micro-grid areas. Both of networks are assumed to have non-identical distributed generator behavior with different parameters. The prime mover and speed governor systems are augmented with the general swing equation. The tie line model and the information of rotor angle was considered. Then, in the last section, the comparison between this technique with the conventional approach using centre of inertia (COI) technique was defined.

“…Thus, the conjunction of high inertia power sources with the inertia-less sources challenges the operational stability. In order to address these issues, powersharing integrated load shedding strategy is executed to enhance the performance of the microgrid [5,6]. A twophase droop based frequency control and a load shedding strategy are analyzed in [5] to maintain the stability of an autonomous microgrid.…”

Recently microgrids have drawn a potential attraction by fulfilling the environmental demands and the increasing energy demands of the end-users. It is necessary to focus on various protection and control aspects of a microgrid. During the transition between the grid-following and grid-forming modes, the voltage and the frequency instability due to the power mismatch condition becomes the major point of concern. Therefore, the paper executes a frequency-active power and voltage-reactive power drooping control strategy for the precise power-sharing among the distributed power generators. Furthermore, to handle the power deficit scenarios and to maintain the system stability, a system independent and priority-based adaptive three-stage load shedding strategy is proposed. The sensitivity of the strategy depends on the system inertia and is computed according to the varying absolute rate-of-change-of-frequency. The strategy incorporates the operation of battery storage system and distributed static compensator (D-STATCOM) in the microgrid, to provide a reliable power supply to the customers for a considerable time instead of a sudden load shedding. The effectiveness of the proposed strategies is investigated on a scaled-down modified IEEE 13-bus microgrid system on the podium of MATLAB 2015b through the time-domain simulation.

“…Further, analyzing all systems, we verify the impact of a good data protocol development, so the information necessary to define the expected behavior of the agents could be sent to their recipients. As described in [37], there are some control methodologies for microgrid during islanded operation, like voltage and frequency management, power quality, droop control and balance between supply and demand. The focus of this paper is in the last methodology.…”

This paper presents a framework to analyze the problem of real-time management of Smart Grids. For this purpose, the energy management is integrated with the power system through a telecommunication system. The use of Multiagent Systems (MAS) leads the proposed algorithm to find the best-integrated solution, taking into consideration the operating scenario and the system characteristics. With this framework it was possible to evaluate the design of the energy management and the impact of the algorithm developed in the MAS. In the same way, the data sent from the power system to be used for energy management have a direct impact on his behavior. The proposed framework is tested with the help of a microgrid, so the results may be replicated.
