The present paper develops a model to optimize the daily operation of a hybrid energy system consisting of a hydrokinetic, a pumped hydro storage system and a diesel generator. The optimization approach is aimed at minimizing the cost function subject to the availability of water resource, the variable load requirements, and operational constraints of the hybrid system's components. The main purpose...
The outback of Australia is characterised by its remoteness from traditional electrical energy supplies and vast distances between inhabited areas which impede supply of commodities. Insular power systems are typical solutions for such localities, usually consisting of a generator energised by diesel fuel or liquefied petroleum gas. In this paper an enhanced, hybrid system is considered by adding...
Decentralised power generation systems based on renewable energy can play an important role in hastening electrification of isolated areas in developing countries.

Stand-alone generators are mostly used to deliver power to consumers in isolated remote locations or rural communities, which usually increase the cost of energy generation. Solar photovoltaic (PV) systems are experiencing a world-wide rapid take-up due to their rapidly reducing cost and climate-friendly attributes. This study aims to develop a PV-Diesel hybrid power system for the remote township...
In this work, an optimal scheduling model is developed to minimize the operation cost of solar photovoltaic-diesel-battery hybrid systems. Furthermore, two operation modes of the diesel generator, namely the "ON-OFF" and the "CONTINUOUS", are modeled and integrated in the hybrid system operation mode. The principal objective of these developed models is to minimize the hybrid system's...

Electricity being an integral part of modern age technology, is an imperative element for sustainable development. Using fossil fuel for the generation of electricity has been the norm but alarming reasons such as depletion of fossil fuel at an increased pace and their tremendous negative impact on environment have led to growing interest in using renewable resources for generating electricity which...
This paper looks at multiple energy sources now available at the cell site, as well as design and management complexities that have risen as a result. The goal of this paper is to outline design considerations for each alternative energy source, such as technologies, logistics, setup and operation. By showing these considerations, decision-makers can refine objectives for deployment and operation,...
BTS sites are subject to constant cost pressure. Operational cost and especially Diesel consumption form ever increasing cost components.
