Heat extraction mode, e.g. well layout or arrangement of wells, of enhanced or engineered geothermal system (EGS) is crucial to its performance and directly affects its commercial viability. Assuming the subsurface target hot dry rock (HDR) has been well-fractured and the created heat reservoir...

In the face of increasingly stringent pollutant emission regulations, designing an agricultural holding becomes a difficult challenge of connecting a large number of coefficients that describe an energy system of a farm in regard to its ecological and economic efficiency. One way to cope with...

Thermal energy storage plays an important role in extending the operation of a concentrating solar power (CSP) plant to times when sufficient solar energy is unavailable for generation of electricity. Extending the CSP plant operation increases its capacity factor and can lead to reduction in...

This paper presents a methodology for sizing and simulating an autonomous photovoltaic-wind hybrid energy system with battery storage, using simulation tools and linear programming. The developed model is useful for energizing remote rural areas and produces a system with minimum cost and high...

The gas system in Europe is facing increasing unpredictability due to the interactions with the electricity generation system. Indeed, gas fired power plants make up an important back-up technology to deal with intermittency induced by wind-power integration. Therefore, the flexibility needs...

To balance the demand and supply at off-peak hours, nuclear power plants often have to be down-regulated particularly when the installations exceed the base load requirements. Part-load operations not only increase the electricity cost but also impose a detrimental effect on the safety and...

A strong and intermeshed electricity grid allows the cost-efficient achievement of renewable energy targets by enabling the use of favorable sites and by facilitating the balancing of stochastic infeed from renewables and electricity demand. However, construction of new lines is currently...

Throughout the last years the use of on-site renewable energy sources (RES) in residential houses has continuously increased in many industrial countries and it is expected that many of the supply systems will be based solely on renewable sources in the medium term future. However, the...
