A recently developed state-of-the-art agent-based simulation of power distribution systems is capable of modeling the thermal and demand response behavior of many thousands of thermostatic end-use loads. It computes the total power consumed by electric power customers when responding to real-time prices. Investigation of the initialization transients has led to a more precise understanding of t...

with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

The growing concern about global climatic changes and fossil fuel depletion calls for a shift from conventional modes of transportation to electric vehicles (EV). The idea of bidirectional interaction between grid and Electric vehicle has brought the V2G ,V2H etc. technologies . Bidirectional chargers adds the benefit of EVs by enabling energy transfer from vehicle to grid (V2G) or vehicle to h...

– We introduce a model for the dynamic self-organization of the electric grid. The model is characterized by a conserved magnitude, energy, that can travel following the links of the network to satisfy nodes’ load. The load fluctuates in time causing local overloads that drive the dynamic evolution of the network topology. Our model displays a transition from a fully connected network to a conf...

This paper presents a multiobjective linear integer programming model for supporting the choice of remote load control strategies in electric distribution network management. The model takes into account the main concerns in load management, considering three objective functions: minimization of the peak demand as perceived by the distribution network dispatch center, maximization of the utilit...

Electric power industry deregulation has forced utilities to perform studies to determine the changes that should be made for efficiency improvements, cost reductions, and power quality enhancements. At the distribution system level, there are a number of attributes can influence the system operation performance. To fully evaluate the distribution network operation performance, a distribution p...

This paper discusses the Dynamic voltage restorer (DVR) operation and control for Voltage sags compensation. DVR is a series connected power electronic based device that can quickly mitigate the voltage sags in the system and restore the load voltage to the pre-fault value. Voltage sag associated with faults in transmission and distribution systems, energizing of transformers, and starting of l...

Short-term load forecasting (STLF) plays an important role in the operational planning security functions of an energy management system. The short term load forecasting is aimed at predicting electric loads for a period of minutes, hours, days or week for the purpose of providing fundamental load profiles to the system. The work presented in this paper makes use of PSO based local linear wavel...
