The mean variance mapping optimization technique (MVMO) is employed in this paper to solve the economic dispatch problem (ED) in power systems. The effectiveness of the proposed technique has been verified on three different case studies to solve the ED problem of thermal power units taking into account the transmission losses and other constraints which include generation limits, ramp rate limits,...
This paper focuses on the power management of renewable energy based distributed generators (RDGs) installed in medium voltage distribution networks (DNs). The goal of the study is to propose a strategy that improves the operation of the distribution network by utilizing the available resources efficiently. This is achieved by continuously managing the output power from the RDGs to meet the required...
This paper presents a two-stage method for the placement of Phasor Measurement Units (PMUs) to achieve a fully observable power system while considering the PMUs channel limitation. The first stage uses the Binary Integer Linear Programming (BILP) to find the initial optimum locations of PMUs which ensure full system observability under normal conditions. The second stage uses state enumeration based...
This paper presents a power management strategy for islanded microgrids. The proposed strategy utilizes the MultiAgent System (MAS) to perform the required tasks. The strategy is divided into two stages. The first stage is an operational planning stage which aims to optimize the operation of the microgrid in the islanded mode. This is achieved by performing Optimal Power Flow (OPF) periodically in...
This paper presents a fully decentralized coordination strategy based on Multi-Agent System (MAS) for voltage regulation in active distribution networks (ADNs). The strategy is based on coordinating the operation of Distributed Generators (DGs) and On-Load Tap Changer (OLTC) to maintain the bus voltages within acceptable limits. The strategy attempts to maximize the use of the renewable based DGs...
This paper investigates the reliability of different topologies of grid connected photovoltaic (PV) systems. The topologies considered in this study are centralized topology, string topology and multi-string topology. The reliability of each topology is evaluated by using suitable reliability indices that are based on calculating the probability of different operating states. These states are evaluated...
Analyzing the impacts of large on-grid photovoltaic (PV) systems on the performance of the electric network is an essential task prior to the installation of these systems. To quantify these impacts, a method based on chronological simulations can be used. The main advantage of this method is its ability to provide information about the impacts of the fluctuation of the power generated from the PV...
