economic analysis of power generation from parabolic trough solar Thermal Plants for the mediterranean region a case study for the island of cyprus
Renewable & Sustainable Energy Reviews, 2009Co-Authors: Andreas PoullikkasAbstract:In this work a feasibility study is carried out in order to investigate whether the installation of a parabolic trough solar Thermal technology for power generation in the Mediterranean region is economically feasible. The case study takes into account the available solar potential for Cyprus, as well as all available data concerning current renewable energy sources policy of the Cyprus Government, including the relevant feed-in tariff. In order to identify the least cost feasible option for the installation of the parabolic trough solar Thermal Plant a parametric cost-benefit analysis is carried out by varying parameters, such as, parabolic trough solar Thermal Plant capacity, parabolic trough solar Thermal capital investment, operating hours, carbon dioxide emission trading system price, etc. For all above cases the electricity unit cost or benefit before tax, as well as after tax cash flow, net present value, internal rate of return and payback period are calculated. The results indicate that under certain conditions such projects can be profitable.

Economic analysis of power generation from parabolic trough solar Thermal Plants for the Mediterranean region—A case study for the island of Cyprus
Renewable and Sustainable Energy Reviews, 2009Co-Authors: Andreas PoullikkasAbstract:Abstract In this work a feasibility study is carried out in order to investigate whether the installation of a parabolic trough solar Thermal technology for power generation in the Mediterranean region is economically feasible. The case study takes into account the available solar potential for Cyprus, as well as all available data concerning current renewable energy sources policy of the Cyprus Government, including the relevant feed-in tariff. In order to identify the least cost feasible option for the installation of the parabolic trough solar Thermal Plant a parametric cost–benefit analysis is carried out by varying parameters, such as, parabolic trough solar Thermal Plant capacity, parabolic trough solar Thermal capital investment, operating hours, carbon dioxide emission trading system price, etc. For all above cases the electricity unit cost or benefit before tax, as well as after tax cash flow, net present value, internal rate of return and payback period are calculated.

The simulation of transients in Thermal Plant. Part II: Applications
Applied Thermal Engineering, 2007Co-Authors: Gian Luca Morini, S. PivaAbstract:Abstract This paper deals with the simulation of the transients of Thermal Plant with control systems. In the companion paper forming part I of this article [G.L. Morini, S. Piva, The simulation of transients in Thermal Plant. Part I: Mathematical model, Applied Thermal Engineering 27 (2007) 2138–2144] it has been described how a “Thermal-library” of customised blocks can be built and used, in an intuitive way, to study the transients of any kind of Thermal Plant. Each component of Plant such as valves, boilers, and pumps, is represented by a single block. In this paper, the “Thermal-library” approach is demonstrated by the analysis of the dynamic behaviour of a central heating Plant of a typical apartment house during a sinusoidal variation of the external temperature. A comparison of the behaviour of such a Plant with three way valve working either in flow rate or in temperature control, is presented and discussed. Finally, the results show the delaying effect of the Thermal capacity of the building on the performance of the control system.

The simulation of transients in Thermal Plant. Part I: Mathematical model
Applied Thermal Engineering, 2007Co-Authors: Gian Luca Morini, S. PivaAbstract:Abstract This paper deals with the simulation of the transient behaviour of Thermal Plant with control systems. It is always more difficult for a designer to predict the effects on the Plant of the control processes because of the increasing complexity of Plants and control systems. The easiest way to obtain information about the dynamic behaviour of a Thermal Plant at the design-stage involves assessing the suitability of specific computer codes. To this end, the present work demonstrates that nowadays it is possible, by using the opportunities offered by some general purpose calculation systems, to obtain such significant information. It is described how a “Thermal-library” of customized blocks (one for each component of a Thermal Plant such as valves, boilers, and pumps) can be built and used, in an intuitive way, to study any kind of Plant. As an example, the dynamic behaviour of a residential heating system will be shown in a companion paper, forming part II of the present article.

increasing Thermal Plant flexibility in a high renewables power system
Applied Energy, 2015Co-Authors: M L Kubik, Phil Coker, Janet F BarlowAbstract:Thermal generation is a vital component of mature and reliable electricity markets. As the share of renewable electricity in such markets grows, so too do the challenges associated with its variability. Proposed solutions to these challenges typically focus on alternatives to primary generation, such as energy storage, demand side management, or increased interconnection. Less attention is given to the demands placed on conventional Thermal generation or its potential for increased flexibility. However, for the foreseeable future, conventional Plants will have to operate alongside new renewables and have an essential role in accommodating increasing supply-side variability. This paper explores the role that conventional generation has to play in managing variability through the sub-system case study of Northern Ireland, identifying the significance of specific Plant characteristics for reliable system operation. Particular attention is given to the challenges of wind ramping and the need to avoid excessive wind curtailment. Potential for conflict is identified with the role for conventional Plant in addressing these two challenges. Market specific strategies for using the existing fleet of generation to reduce the impact of renewable resource variability are proposed, and wider lessons from the approach taken are identified.
