Intentional islanding is a feasible solution to improve the reliability of the smart distribution system with distributed generations (DGs) when the electrical connections between the smart distribution system and upstream network are lost. In this paper, a heuristic method is proposed for the intentional islanding of microgrids. In this method, some practical and important factors such as redu...

The satisfaction of electricity customers and environmental constraints imposed have made the trend towards renewable energies making them more essential due to their advantages as reducing power losses ameliorating system’s voltage profiles reliability. This article addresses optimal location size multiple distributed generations (DGs) based on solar photovoltaic panels (PV) connected electric...

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...

Optimal reactive power dispatch (ORPD) has a crucial impact to enhance safety, reliability, and economical operation of the electric system. ORPD is non-linear, non-convex mixed variable problem, which been solved by many researchers via different meta-heuristic algorithms during last decade. In this work, novel algorithm named sine-cosine (SCA) utilized solve problem considering both dependent...

This paper proposes a reliability-based optimal scheduling model of integrated microgrids. The proposed is capable delivering each individual microgrid and aggregated system. In addition, it compatible with both grid-connected islanded operation modes. developed problem formulation the takes into account reliability indices SAIDI, SAIFI, CAIDI to evaluate Numerical simulations on modified IEEE-...

The incorporation of a tie-line between two areas may be beneficial in ways. First, the reserve capacity assisting area support to assisted area, and second, number Phasor Measurement Unit (PMU) requirements will become smaller for complete observability interconnected grid. objective function is formulated integrate reliability analysis synchrophasor networks. effect Zero Injection Bus (ZIB) i...

In this paper, the new approach for the transmission reliability cost allocation (TRCA) problem is proposed. In the conventional TRCA problem, for calculating the contribution of each user (generators & loads or contracts) in the reliability margin of each transmission line, the outage analysis is performed for all system contingencies. It is obvious that this analysis is very time-consuming fo...
