The human demand for electricity and fresh water is ever increasing. Due to the nature of hydropower and its economic, social, and environmental benefits, hydropower will be an important contributor to the energy mix of the future. Isolated areas, severely underdeveloped regions, disaster-stricken zones, and remote military outposts have one common need: readily available and efficient means of...

Microwave-assisted hydro distillation MAHD of eucalyptus citriodora. oil was investigated and a comparison was made with conventional hydro distillation. For MAHD, three process parameters; Microwave power, Extraction time and duration of dryness of sample were selected for the extraction. MAHD resulted in a shorter extraction time and better quality of oil compared to that in conventional hydr...

In order to meet the challenges brought by high penetration of intermittent and fluctuating wind solar power, a short-term optimal scheduling model for wind-solar-hydro hybrid generation system with cascade hydropower is established objective minimizing amount abandoned wind, hydro power maximizing stored energy stations. Cascade considered provide spinning reserve regulation ensure security sy...

In this paper a novel stochastic fundamental European electricity market model (E2M2s) is applied to estimate the value of electricity produced by wind turbines. The principle of E2M2s is cost minimisation in the European power network. The model determines the marginal system costs mainly as a function of available generation and transmission capacities, primary energy prices, plant characteri...

Several interconnected power systems worldwide have largely thermal and hydro production along with CO2 cap-and-trade (C&T) variable renewable energy sources (VRES). C&T policies increase VRES generation, socially optimal storage deployment could integrate output. However, reservoirs may be used strategically due to market power. We investigate these distortions assess measures for their mitiga...

This paper considers a condition-based maintenance (i.e. CBM) model for the hydro generating unit in the deregulated power system. As the downtime cost of the generating unit varies according to the time-varying electricity price, the economic dependence among the critical component of the generating unit is dynamic. In this paper, the proposed DynamicEconomic-Dependence and proportional hazard...

For a stable supply of electricity power plants are required to provide ancillary services in addition to energy production. This paper suggests a solution for optimal bidding strategy for hydroelectric units operating in markets where both energy and ancillary services are priced simultaneously. The model is illustrated on a numerical example of a hydro unit operating in such markets of New Yo...
