The implementation of major equipment within an existing electrical system necessitates a thorough comprehension of environmental policies, integrated planning, and organizational interaction in the sphere of the endeavor. In a hydroelectric energy system integration methodology, there are various optional processes and detailed analysis encountered throughout the execution. The selection of a ...

In order to meet ever-increasing customer service expectations, electric utilities must continuously improve the reliability of their electric distribution systems. Over the last decade, utilities have invested in digital technologies that give them near-real time readings on the health of their electric grid. This data is incredibly useful during major storm outages, but the flood of data pour...

This paper presents optimal phasor measurement units (PMUs) placement algorithms for power system observability. The optimal placement problem (OPP) is formulated such that minimizing the number of PMU installations for full network observability. Three approaches, in this paper, are introduced aiming at reducing the computational burden in Optimal Placement problems. Depth First Search, Simula...

A networked dynamical system consists of numerous loosely coupled systems. These networked systems are found throughout our national infrastructure in the guise of our electrical power grid and transportation networks. Interruptions in the smooth operation of these networks can disrupt the lives of millions of users. Increased demand due to demographic shifts and greater regulatory burdens have...

This article describes the methodology for evaluation of the reliability of an composite electrical power system considering voltage stability and continuation power flow, which takes into account the peak load and steady state stability limit. The voltage stability is obtained for the probable outage of transmission lines and removal of generators along with the combined state probabilities. T...

Electricity powers the economic system. Households need stable electricity since many tasks require it1. Pakistan had frequent power outages for decades. The monopolistic supplier used cyclical load shedding over hours a day in much of country to avoid unplanned blackouts and meet demand due production losses. Load occurs when exceeds supply2. Pakistan's major resource heating, cooking, lightin...

In this paper, educational software for the reliability assessment of high/medium-voltage (HV/MV) substations and distribution feeders is presented. It is a useful tool for learning the utility of reliability indices of the HV/MV substations and their distribution feeders, and their influence on the electrical power system operation. By means of an interactive graphical interface, multiple conf...

This paper addresses the problem of predicting duration of unplanned power outages, using historical outage records to train a series of neural network predictors. The initial duration prediction is made based on environmental factors, and it is updated based on incoming field reports using natural language processing to automatically analyze the text. Experiments using 15 years of outage recor...

In this contribution, we present the development of DynaSCOPE as a fully distributed continuous planning approach for decentralized energy units organized in Dynamic Virtual Power Plants (DVPP). The work at hand elaborates on possible basic algorithms for the DVPP planning task, motivates the choice of a fully distributed algorithm and gives details and evaluation results for the presented syst...
