We describe a stochastic dynamic programming approach for “real option” based valuation of electricity generation capacity incorporating operational constraints and startup costs. Stochastic prices of electricity and fuel are represented by recombining multinomial trees. Generators are modeled as a strip of cross commodity call options with a delay and a cost imposed on each option exercise. We...

Performance, quality and reliability issues are becoming more and more important for the emerging photovoltaic markets worldwide. The purpose of this work is comparing and presenting operational performance results of grid-connected PV systems, as collected and elaborated for Task 2 of the Photovoltaic Power Systems Programme (PVPS) of the International Energy Agency (IEA). The data analysed he...

The betatron squeeze is a critical operational phase for the LHC because it is carried out at top energy, with the maximum stored energy and with reduced aperture margins in the superconduting triplets. A stable operation with minimum beam losses must be achieved in order to ensure a safe and efficient operation. The operational experience at the LHC showed that this is possible. The operation ...

Both of berth allocation and quay crane assignment are one of the most complex parts in container terminal operations, which significantly affect the operational efficiency, energy consumption and operational cost of the entire container terminal. Therefore, it is necessary to develop an efficient strategy for integrated berth allocation and quay crane assignment (BACP) from the perspective of ...

As the share of wind energy increases on the global energy market, the efficient operation of wind farms gains an ever growing significance. Among operational decisions, the planning and scheduling of maintenance operations are crucial for the availability of turbines, as well as for the operational costs. The paper introduces a system that performs the detailed scheduling of maintenance operat...

A new modified configuration for the stand-alone photovoltaic (PV) system to electrify a remote area household load in Egypt is presented. The modeling, simulation, and operational control strategy for the system is developed. The developed control aims to optimize the energy flow within the system, such that the load is satisfied independent on the variations in insolation. Also, it aims to pr...

The UK Water Industry currently generates approximately 800 GWh pa of electrical energy from sewage sludge, a renewable by-product from wastewater treatment. Advanced anaerobic digestion processes are beginning to improve energy yields from this resource which the industry has in abundance. These processes are being implemented across the UK and within Thames Water. However, these processes are...

The wireless sensor networks consist of hundreds of inexpensive wireless nodes, each with some computational power and sensing capability, operational power and sensing capability, operating in an unattended mode. Clustering is an efficient approach to capitalize the energy of energy constraint sensor nodes in wireless sensor networks (WSNs). Low Energy Adaptive Clustering Hierarchy (LEACH) is ...

This paper deals with the joint planning and energy management operation of Wireless Mesh Networks. We claim that energy management should be incorporated at the planning stages to produce an effective energy-management operation. For this, we propose a mathematical framework that takes into account the trade-off of capital expenditures versus energy-related operational ones when designing the ...
