this paper investigates the islands formation in initial stages of restoration process in blackout condition and studies the impacts of islands number variation on the process execution. in addition, a method is proposed to determining each island optimal boundaries. then the effects of transmission lines thyistor controlled series compensators (tcsc) to facilitate restoration process and impro...

In this paper, effect of the islands number variation in restoration process is investigated and a graph based method for determination of optimum islands boundaries is presented. Also, the effect of number and location of black-start units on the restoration process is evaluated. In optimization process, objective function is minimizing Energy Not Supplied (ENS) and constraints are voltage mar...

this paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. the method considers both the spinning reserve and interruptible loads as the operating reserve services. in the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...

In this paper, a multi-objective reconfiguration problem has been solved simultaneously by a modified ant colony optimization algorithm. Two objective functions, real power loss and energy not supplied index (ENS), were utilized. Multi-objective modified ant colony optimization algorithm has been generated by adding non-dominated sorting technique and changing the pheromone updating rule of ori...

This article presents an optimal placement and sizing of distribution static compensator (DSTATCOM) in radial networks as multi-objective optimization with the objective power loss reduction, voltage profile improvement network reliability considering different variable demands using whale algorithm (WOA). The WOA is inspired by hunting behavior humpback whales. location size DSTATCOM are consi...

On the topic of power systems, most critical assignment would be providing facilities to make electricity available at lowest price with a fulfilled level reliability for all consumers. Today, transmission has received more concentration due increasing essence high-quality energy customers and operating competitive conditions in markets. In this regard, paper scrutinizes reliability-centred mai...

This paper presents a fuzzy system for reliability-based power distribution network planning. The proposed Mamdani type inference with subsequent application of the Bellman-Zadeh decision-making method is used to evaluate reliability line feeders as criteria Unplanned outages components, Energy Not Supplied (ENS) and age lines are input variables fuzzified using triangular functions. model was ...

This paper provides an optimal approach to denote the location and size of ESSs (energy storage systems) with the intention of reliability improvement in radial electrical distribution networks. The proposed optimal ESSs planning is addressed as a minimization problemwhich aims at minimizing the cost of ENS (energy not supplied) as well as ESSs costs at the same time, subject to safe operation ...
