This paper presents new solution methods and results based on a refined binary particle swarm optimization (RBPSO) for solving the generation/pumping scheduling problem within the power system operation with pumped-storage units. The proposed RBPSO approach combines a basic particle swarm optimization (PSO) with binary encoding/decoding techniques. Complete solution algorithms and encoding/deco...

Multienergy complementation is an important means to improve the capacity of renewable energy consumption and key achieving goal “net zero” globally. The hydro–wind–photovoltaic-storage hybrid system technical approach, in this system, pumped storage battery are both components for regulation. To study problem coordinated control two systems, a model storage-battery integrated (PSBIS) simulatin...

Surplus electricity can be converted into potential energy via pumped hydroelectric storage for future usage. Similarly, thermo-electric energy storage (TEES) uses heat pumps equipped with thermal storage to convert electrical energy into thermal energy; the stored energy is then converted back into electrical energy when necessary using a heat engine. The greatest advantage of this method is t...

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 ...

This paper presents a novel method based on an enhanced firefly algorithm (EFA) to solve scheduling hybrid thermal, pumped-storage, and wind plants. Since the problem is inherently discrete, basic EFA binary encoding/decoding techniques are used in proposed approach. Optimal power values of thermal pumped-storage units determined separately presence uncertainty caused by speed. The applied real...

An optimal dispatching strategy for a multi-source complementary power generation system taking source–load uncertainty into account is proposed, in order to address the effects of large-scale intermittent renewable energy consumption and load instability on grid dispatching. The problem first converted common situations study, such as forecasting solar wind power. backward scenario reduction L...

This paper contributes towards exploring the technical and institutional feasibility of small hydropower storage and pumped-storage schemes in Switzerland. Within the European and Swiss context of the facilitation of renewable energy technologies, which includes small hydropower (SHP), intermittent sources such as solar and wind increase the need for additional energy storage capacities. Hydrop...

The integration of wind power in power systems results in a reduction in greenhouse gas emissions. Thus, it has a positive environmental impact. However, the operation of these power systems becomes increasingly complex, owing mainly to random behaviour of the wind. In the case of island power systems, this problem is even more difficult. The traditional solution is to use diesel generators as ...

It is very important, to optimize of clean electrical energy by employing of variable Speed pumped storage power plant (VSPSP). Variable speed machines are used extensively in wind power plants and pumped storage power plants. Therefore, the advantages of this technology are including: stability, reliability, fast dynamic responses, frequency control and high efficiency of power system. By usin...
