The impact of different energy storages on power systems has become more important due to the development of energy storage technologies. This paper optimizes the stochastic scheduling of a wind-based multiple energy system (MES) and evaluates the operation of the proposed system in combination with electrical and thermal demand-response programs and the three-mode CAES (TM-CAES) unit. The prop...

Storage of electrical energy is a key technology for future climate-neutral supply with volatile photovoltaic and wind generation. Besides the well-known technologies pumped hydro, power-to-gas-to-power batteries, contribution thermal storage rather unknown. At end 2019 worldwide power generation capacity from molten salt in concentrating solar (CSP) plants was 21 GWhel. This article gives an o...

Sustainability of the future energy supply based on renewable resources is a long-term strategic objective [1] in view of limited fossil resources and the avoidance of emissions and toxic waste. Of the various resources, available now or in future, wind is presently considered in Europe to hold most promise for contributing in the next few decades a sizeable part of the electrical energy; gener...

This paper addresses a multistage stochastic model for the optimal operation of wind farm, pumped storage and thermal power plants. The output of the wind farm and the electrical demand are considered as two independent stochastic processes. The evolution of these processes over time is modeled as a scenario tree. Considering all possible realizations of stochastic process, leads to a huge set ...

This paper examines the operation of the Irish power system with very high levels of wind energy, with and without pumped storage. A unit commitment model which accounts for the uncertainty in wind power is used. It is shown that as wind penetration increases, the optimal operation of storage depends on wind output as well as load. The main benefit from storage is shown to be a decrease in wind...

This paper discusses the power generation characteristics between new energy and traditional energy. uses different alliance operation modes for a system led by generation. The peak-valley imbalance issue real-time load is mitigated through coordinated optimized supply wind, photovoltaic, hydro (hydropower station with pumped storage function as an example.), thermal power, aiming to peak shift...

The increasing use of renewable energy technologies for electricity generation, many of which have an unpredictably intermittent nature, will inevitably lead to a greater need for electricity storage. Although there are many existing and emerging storage technologies, most have limitations in terms of geographical constraints, high capital cost or low cycle life, and few are of sufficient scale...
