in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...

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...

background and aims. anterior esthetic restoration is challenging in pediatric dentistry, due to limited durability and poor retention of the restoration.this study assessed the effect of air abrasion on tensile failure load of composite class iii restorations using different preparation techniques. materials and methods. 100 extracted human anterior primary teeth were divided, based on the pre...

Restoration of distribution system in cold weather and after long interruptions creates cold load pickup problem due to loss of diversity among the loads in residential area. Under such conditions the distribution system load may have to be restored step by step, using sectionalizing switches to prevent overheating of substation transformer. The order in which the sections are restored has a si...

In the event of a major network outage such as a ber cable cut, a network can experience signiicant deterioration of network performance. To address such a situation, a network can be equipped with restoration capacity. We present here a mathematical model and design algorithm for determination of transmission network restoration capacity. We then present models for two restoration options { co...

Effect of load variation on network reconfiguration and service restoration plans in balanced and unbalanced distribution systems is studied. Comprehensive survey of the conceptual aspect as well as published algorithms for distribution network reconfiguration is presented. Different reconfiguration networks and scenarios are discussed. Results showed the effectiveness of building restoration p...

Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions.  The proposed strategy balances single-phase...
