Modeling of a microgrid’s power generation cost function in real-time operation for a highly fluctuating load
Fares S. El-Faouri,Mustafa Walid Alzahlan,Majd Ghazi Batarseh,Ahmad A. Mohammad,Muhy Eddin Za'ter +4 more
TL;DR: A novel real-time monitoring operation model of a microgrid is suggested, where the overall cost is mathematically modeled and included in the proposed model and the inclusion of imported power from neighboring microgrids is implied.

Coordinated AVR and tap changing control for an autonomous industrial power system
TL;DR: In this paper, a strategy for voltage and reactive power control of an autonomous industrial power system including distributed generators and loads is presented based on time-domain simulations and aims to define the main functions for the power management system (PMS) that will govern the operation of the power system.

Medium-voltage distribution network expansion planning with gene-pool optimal mixing evolutionary algorithms
TL;DR: The results show that the favorable performance of GOMEA instances over traditional GAs extends to the real-world problem at hand, and the use of linkage learning is shown to further increase the algorithm’s effectiveness in converging toward optimal solutions.

Reactive power management strategies in future smart grids
TL;DR: In this article, several reactive power control strategies considering a smart grid paradigm are proposed and implemented in a MAS simulation tool, and the proposed methods have been computationally implemented and tested using a 32-bus distribution network with intensive use of distributed resources, mainly the distributed generation based on renewable resources.

Electric Energy Systems—An Overview
TL;DR: The first electric light systems, installed around 1870, consisted of individual dynamos that fed the electrical system in a single residence as mentioned in this paper, and the first electric current was first transmitted in 1884 at a voltage of 18 kV.
