Power outages cost American industries and businesses billions of dollars and jeopardize the lives of hospital patients. The losses can be greatly reduced with a fast, reliable, and flexible self-healing tool. This paper is aimed to tackle the challenging task of developing an adaptive restoration decision support system (RDSS). The proposed RDSS determines restoration actions both in planning and...
Traditionally, distribution system takes a long time to recover after a major outage, due to its top-down operation strategy. As fast response energy resources, Plug-in Hybrid Electric Vehicles (PHEVs) can accelerate the load pickup process by compensating the imbalance between available generation and load in distribution system. In this paper, PHEVs are employed for reliable load pickup and faster...
Data centers are becoming a significant energy consumer. Server workload, cooling, and supporting infrastructure represents large loads for the grid. This paper intends to present a comprehensive literature review that account for generation, loads, storage, and topology of data centers. It is shown that green data centers are emerging which incorporate renewable energy sources to cap their carbon...
Solar is the fastest growing source of renewable electricity in the U.S. The anticipated PV proliferation brings integration challenges on system volt/var performance at the utility scale. One of the greatest challenges is to maintain desirable feeder voltages in utility distribution networks. The intermittent PV generation causes more frequent operation of volt/var control (VVC) devices to alleviate...
PMU placement is important to achieve full system observability. Traditional PMU placement algorithms only work for systems in normal condition. During power system restoration, system topology and condition change in each step. Synchrophsors can help to improve the reliability and efficiency of restoration strategy. However, the original PMU placement cannot guarantee system observability in each...
Future planned expansion of Tehran power network depicts that two new generating stations will be installed which result in the increase of short-circuit capacity at some of the grid substations in excess of the interrupting rating of exiting circuit breakers. Various measures regarding short-circuit current mitigation for high voltage application have been proposed in many literatures. This paper...
Future's load and generation model of Tehran power network depicts fast increase in demand and development of power network. By 2015, Two new generating stations are expected to be installed which result in the increase of short-circuit capacity of a few substations in excess of the interrupting rating of exiting circuit breakers. This paper intends to analyze the consequences of employing thyristor...
