“…Nowadays PV/wind‐based HES along with the internal combustion engine for back‐up energy source, is integrated with PHS for reliable and smooth power supply. Many researchers also carried out research studies on hybrid‐PHS configurations 16,128‐130,133‐141,144,148,219 . Results from the above literature, it can be summarized that the integrated system has some features of increased round‐trip efficiency, reliability of the power supply, reduced revenue losses, cost savings, low investment cost, maximum accessible energy, higher life span, and reduced greenhouse emission compared to a battery and other storage systems.…”

“…The objective of the model was to reduce the cost of the system by using a diesel generator and PV energy. Liu et al 136 developed an optimal operational model of the autonomous local power grid with numerous PV/wind/hydro/battery power based on the statistical data of the wind/PV using PSO. The system demonstrated desired performance while supplying water toward the end of the dry season for continuous electricity generation in hydropower stations.…”

The integration of storage technologies into the hybrid energy system (HES) offers significant stability in delivering electricity to a remote community. In addition, the benefits of using storage devices for achieving high renewable energy (RE) contribution to the total energy supply are also paramount. The present study provides a detailed review on the utilization of pump‐hydro storage (PHS) related to the RE‐based stand‐alone and grid‐connected HESs. The PHS‐based HESs have been analyzed considering the technical details, including reliability, cost‐effectiveness, and environmental indicators. The optimization techniques are critically employed to the PHS‐based systems, including metaheuristics intelligent techniques, commercially available optimization and simulation tools, and recent advanced optimization tools. A comparative analysis of PHS integration to the stand‐alone and grid‐connected systems based on techno‐economic and environmental indicators over other storage technologies is also presented. The key technical and environmental challenges related to the PHS‐based HES are identified. Results from the recent research studies indicate that the PHS‐based HESs offer significant cost and environmental benefits over battery storage technologies. The study identifies that the particle swarm optimization is the mostly appreciated optimizing technique for cost‐effective energy supply and environmental aspects followed by hybrid optimization model for electric renewables and genetic algorithm.

“…In recent years, the modeling and optimization of complementary power generation system between renewable energy and other power have been conducted in many studies, mainly including hydro-wind (Denault et al, 2009;Lopes and Borges, 2014;Bayon et al, 2016;Shayesteh et al, 2016), hydrosolar-wind (Schmidt et al, 2016;Liu et al, 2019;, hydro-wind-thermal (Zhou et al, 2016;Zhang et al, 2017), solar-wind-pumped storage (Jakub et al, 2018;Xu et al, 2019), and wind-solar-storage (Lee and Wang, 2008;Lasemi and Arabkoohsar, 2020). The main idea is to combine renewable energy with hydropower and other flexible power and then improve the power grid's ability to consume renewable energy and schedulability.…”

A Two-Stage Dispatching Method for Wind-Hydropower-Pumped Storage Integrated Power Systems

With the fossil energy crisis and environmental pollution, wind energy and other renewable energy have been booming. However, the strong intermittence and volatility of wind power make difficult of its integration into grid. To solve this problem, this study proposes a complementary power generation model of wind-hydropower-pumped storage systems, which uses hydropower and pumped storage to adjust the fluctuation of wind power. How to consider the uncertainty and unpredictability of wind power output and make more reliable hydropower generation plan and pumped storage generation plan is the key problem to be solved in the grid with the high proportion of renewable energy. The martingale model of forecast evolution is used to describe the uncertainty evolution of wind power in different regions. According to the flexible load in the region, the flexibility index is used to quantify flexibility, and the transaction price is set to be proportional to flexibility. The two-stage framework of day-ahead and real-time dispatching model is then developed. In the day-ahead stage, different regions trade with each other. If the power after trading is imbalanced, it will be supplemented by hydropower and the grid to meet the power demand. In the real-time stage, the pumped storage is added to quickly balance the deviation of wind power and load between the real-time and day-ahead stages. Finally, considering the positive effect of hydropower on wind power consumption in the grid, a benefit allocation method based on improved Shapley value method is proposed. Test cases are simulated to verify the rationality of the proposed dispatching model and the benefit allocation method. After the cooperation of hydropower and pumped storage, the average revenue growth is 3.02%. The improved benefit allocation scheme makes more benefit of hydropower and pumped storage and promotes the cooperation of multi-participants.

“…Those studies are further limited to investigation on (a) batteries other than Li-ion, (b) small-scale (kW to MW range) applications and (c) technical suitability rather than economic viability. For examples, operation scheduling of 1 MWh BESS (NaS) with a wind turbine for an industrial application [35], 2kW/30kWh BESS (VRB) as an energy storage for small grids and stand-alone PV systems [36], optimal operation strategy of 3MW/10MWh BESS (VRB and polysulfide-bromine (PSB)) for energy arbitrage in a wind dominated power system [37], and an optimal operation strategy for a wind-solar-hydro-battery power system for a regional power grid, with a 6MWh BESS particularly managing the peak demand [38]. On the other hand, only a few investigations for the economic suitability of wind-battery systems for grid applications can be found in the literature.…”

The increasing integration of renewable energy sources makes balancing a grid challenging due to their intermittency. Renewable energy can be curtailed especially when production exceeds demand or when there is transmission and/or distribution network congestions within a grid. However, curtailment would become unnecessary with battery storage, provided the battery storage has enough available storage capacity, which can store energy during the time of excess generation and discharge it to the grid once the demand is high during peak times. Hence, stored energy from batteries can potentially offset supply from expensive and environmentally harmful peak plants e.g. open/combined cycle gas turbine. We investigated the techno-economic prospects of the utilisation of curtailed energy from wind with bulk battery storage to replace open and combined cycle gas turbine power plants, by taking the UK as a case study. A techno-economic model to size and optimise a Li-ion type battery was developed. The optimisation aimed to determine at what cost and size the storage can be commercially viable for gridlevel energy applications. Results show that under base case assumptions of a 15% day to day curtailment from wind and £200/kWh battery cost, an optimised battery size of 1.25 GWh could supply 285 GWh peak demand per annum and its corresponding net present value of £22.4m, internal rate of return of 1.7% and a payback period of 14 years could be achieved. However, to achieve the internal rate of return of 8%, a minimum hurdle rate for investment, the cost of battery would need to be below £150/kWh. Sensitivity analyses with parameters such as curtailed wind, depth of discharge, battery efficiency, and cost and income of battery show that all techno-economic parameters considered in this research have significant impacts on the commercial viability of battery storage for grid applications.
