The paper presents an approach on voltage stability analysis of distribution networks for loads of different types. A voltage stability index is proposed for identifying the node, which is most sensitive to voltage collapse. It is shown that the node, at which the value of voltage stability...

This paper proposes a cuckoo search algorithm (CSA) to solve the optimal reactive power dispatch (ORPD) problem in power system operation considering the power loss and voltage deviation. The proposed CSA is a nature inspired algorithm from the cuckoo species laying their eggs in the nest of...

This paper proposes a DC-AC-linked hybrid diesel/photovoltaic (PV)/battery storage system for stand-alone applications. PV is the primary power source. A diesel engine is used as a backup and a battery as storage device. An overall power management strategy is designed to manage power flows...

With the greening of the US power grid most of the available landscape and resource investment lays with residential home owners. Historically homes were not built with green technology in mind. Roof faces do not always face south, nor are they always at optimum angles. Existing homes are often...

In the last decade Autonomous Underwater Vehicles are used in large number. The control issue of these vehicles is very challenging due to uncertain underwater environment. Conventional controllers may fail during operations especially when changes in the system occur, since it is impossible to...

In this paper, thermodynamic study of simple and regenerative gas turbine cycles is exhibited. Firstly, thermodynamic models for both cycles are defined; thermal efficiencies of both cycles are determined, the overall heat transfer coefficient through the heat exchanger is calculated in order to...

An expert system for distribution planning is proposed in this paper. Choosing a best location of a distribution substation and grouping the various load points to be fed from a particular distribution substation has always been a concern to the distribution planners. Here in this paper the...

In this paper, quasi-oppositional teaching-learning based optimization (QOTLBO) is introduced and successfully applied for solving an optimal power flow (OPF) problem in power system incorporating flexible AC transmission systems (FACTS). The main drawback of the original teaching-learning based...

An attempt has been made for the effective application of biogeography based optimization and its modified version to solve load frequency control (LFC) problem. Two-area interconnected multi-unit multi-source power system having thermal, hydro and gas power plant without and with AC-DC link is...

As it is known Microgrid is a miniature grid consist of one or more numbers of same or by different conventional or non-conventional generation sources. Here one can consider Microturbine (MT) as the main source of generation and it may or may not be connected with the main grid. The author...
