“…This study suggested a method using the total revenue requirements for multi-objective optimization by thermodynamic and economic models. A similar study was conducted by Bakelli et al [6]. This study proposed an optimal sizing model to determine the capacities of the components of a photovoltaic water pumping system on the basis of two criteria: the loss of power supply for reliability and the life cycle cost.…”

Simplified Method of Optimal Sizing of a Renewable Energy Hybrid System for Schools

Schools are a suitable public building for renewable energy systems. Renewable energy hybrid systems (REHSs) have recently been introduced in schools following a new national regulation that mandates renewable energy utilization. An REHS combines the common renewable-energy sources such as geothermal heat pumps, solar collectors for water heating, and photovoltaic systems with conventional energy systems (i.e., boilers and air-source heat pumps). Optimal design of an REHS by adequate sizing is not a trivial task because it usually requires intensive work including detailed simulation and demand/supply analysis. This type of simulation-based approach for optimization is difficult to implement in practice. To address this, this paper proposes simplified sizing equations for renewable-energy systems of REHSs. A conventional optimization process is used to calculate the optimal combinations of an REHS for cases of different numbers of classrooms and budgets. On the basis of the results, simplified sizing equations that use only the number of classrooms as the input are proposed by regression analysis. A verification test was carried out using an initial conventional optimization process. The results show that the simplified sizing equations predict similar sizing results to the initial process, consequently showing similar capital costs within a 2% error.

“…In addition, during the year PV generator produces excess energy that can be placed on the market and thus make a profit. The concept of life cycle cost, LCC (€) (Bakelli et al, 2011 andGhoneim, 2006) and netto present value (Markvart andCastaner, 2003 andStevanović andPucar, 2012), is used for the system cost analysis. LCC takes into account the initial capital cost (C capital ), the present value of replacement cost (C replacement ) and the present value of operation and maintenance cost (C operation&maintenance ).…”

This paper describes and analyses new and innovative concepts for possible integration of solar photovoltaic (PV) energy in urban water supply system (UWSS). The proposed system consists of PV generator and invertor, pump station and water reservoir. The system is sized in such a manner that every part of it is sized separately and then, integrated into a whole. This integration is desirable for several reasons; the most important is the success of the objectives of sustainable living in urban areas i.e., achieving of sustainable urban water supply system. The biggest technological challenge associated with the use of solar, wind and other intermittent renewable energy sources RES is the realization of economically and environmentally friendly electric energy storage (EES). The paper elaborates the use of water reservoires in UWSS as EES. The proposed solution is still more expensive than the traditional and, is economically acceptable today in the cases of isolated urban water system and special situations. Wider application will depend on the future trends of energy prices, construction costs of PV generators and needs for CO 2 reduction by urban water infrastructure.Keywords: Urban water supply system, sustainability, solar photovoltaic energy, CO 2 reduction. RESUMENEste artículo describe y analiza conceptos nuevos e innovadores para la posible integración de la energía solar fotovoltaica (PV) en los sistemas de abastecimiento urbano de agua. El sistema propuesto consiste en un generador fotovoltaico y un inversor, una estación de bombeo y un depósito de agua. El sistema se dimensiona de tal forma que cada una de sus partes se clasifica por separado y luego se integran en un todo. Dicha integración es deseable por varias razones: la más importante es el éxito de los objetivos de la vida sostenible en las zonas urbanas, esto es, el desarrollo de un sistema sostenible de abastecimiento urbano de agua. El mayor desafío tecnológico asociado con el uso de energía solar, eólica y otras fuentes de energía renovable intermitentes, es que el almacenamiento de energía eléctrica sea económico y amable con el medio ambiente. En este documento se revisa el uso de reservorios de agua en los sistemas de abastecimiento, como una forma de almacenamiento de energía eléctrica. La solución propuesta es aun más costosa que la tradicional y, hoy en día, es económicamente aceptable en los casos de sistemas aisla-dos de agua urbana y situaciones especiales. Una aplicación más amplia dependerá de las futuras tendencias de los precios de la energía, los costos de construcción de los generadores fotovoltaicos y las necesidades de reducción de CO 2 por la infraestructura de agua urbana. IntroductionThe world today is faced with a growing number of inhabitants who concentrate in all major cities, mostly in the coastal marine zone (Roberts, 2011 andUNEP/PAP, 2007). In an increasingly urbanized world, there is a need to plan and manage our cities in order to sustain them. It is necessary to strive for urban areas that contribute ...

The use of solar energy for water pumping has already been well addressed in literature, for example [8][9][10]. However, at present, there are no significant publications on a more thorough consideration of possible applications of PV generators in UWSS.…”

Abstract:Because of the importance of water supply for the sustainability of urban areas, and due to the significant consumption of energy with prices increasing every day, an alternative solution for sustainable energy supply should be sought in the field of Renewable Energy Sources (RES). An innovative solution as presented in this paper has until now not been comprehensively analyzed. This work presents the solution with the application of a (Photovoltaic) PV generator. The main technological features, in addition to the designing methodology and case study are presented in this paper. The critical period approach has been used for the first time for system sizing. The application of this sizing method provides a high reliability of the proposed system. The obtained results confirm the assumption that the PV generator is a promising energy sustainable solution for urban water supply systems. The service reservoir, which acts as water and energy storage for the proposed system, provides the basis for a sustainable solution of water and energy supply. In accordance with the proposed, the reliability of such system is high. This concept of energy supply operation does not generate any atmospheric emission of greenhouse gases, which contributes significantly to the reduction of the impacts of climate changes. The proposed solution and designing methodology are widely applicable and in accordance with the characteristics of the water supply system and climate. OPEN ACCESS
