Abstract Energy storage plants are going to become a strategic asset in electric grids. This statement is confirmed looking at the increasing shares of renewables composing energy portfolio several nations. Therefore power demand and production mismatches, caused by intermittent nature renewables, must be reconciled. Many solutions available but Advanced Adiabatic Compressed Air Storage (AA-CAE...

The weekly cost-optimal generation of electric power in a hydrothermal generation system is modeled as a multistage mixed-integer stochastic program. The model incorporates uncertainties of electrical load forecasts, of inflows to pumped storage hydro plants and of fuel or electricity prices. For its solution a stochastic Lagrangian relaxation scheme is designed by assigning (stochastic) multip...

The short term cost optimal dispatch of electric power in a generation sys tem under uncertain electricity demand is considered The system comprises thermal and pumped storage hydro units An operation model is developed which represents a multistage mixed integer stochastic program and a conceptual solution method using La grangian relaxation is sketched For xed start up and shut down decisions...

The interest in energy storage is currently increasing, especially from the perspectives of matching intermittent sources of renewable energy with customer demand and storing excess nuclear or thermal power during the daily cycle. Technologies to be considered for load leveling for large-scale energy systems, typically in the range of hours to days of discharge time, include pumped-storage hydr...

This paper investigates the electricity storage requirements to support transition towards a high renewable energy source (RES) penetration in cost-optimal manner. The achieved reduction of curtailments and decrease total generation cost system are quantified against counterfactual scenario without storage. A methodology is presented determine optimum mix short- medium-duration needed operation...

Although wind and solar power is the major reliable renewable energy sources used in grids, fluctuation unpredictability of these require use ancillary services, thereby increasing integration cost. This study proposes a wind, solar, pumped-storage cooperative (WSPC) model that can be applied to large-scale systems connected dispersed sources. provides an optimized coordinated bidding strategy ...

Diode laser-pumped solid-state lasers are efficient, compact, all solid-state sources of coherent optical radiation. Major advances in solid-state laser technology have historically been preceded by advances in pumping technology. The helical flash lamps used to pump early ruby lasers were superseded by the linear flash lamp and arc lamp now used to pump neodymium-doped yttrium-aluminum-garnet ...
