“…Pumping storage plants associated with a secondary plant (which supplies energy for the pumping phase), are called hybrid pumping storage plants (HPHSP). The main HPHSP layouts consider secondary plants based on renewable sources, such as wind [8,13,[24][25][26][27][28][29][30][31], solar [32][33][34][35] or both [9,11,36,37].…”

Pumped hydro storage plants (PHSP) are considered the most mature large-scale energy storage technology. Although Brazil stands out worldwide in terms of hydroelectric power generation, the use of PHSP in the country is practically nonexistent. Considering the advancement of variable renewable sources in the Brazilian electrical mix, and the need to provide flexibility to the national electrical system, several official documents cite PHSP as an important alternative for the expansion of the Brazilian electrical system. This article presents the state of the art of PHSP and its use, in order to create a theoretical basis for future research on the subject, also providing theoretical support for Brazilian energy planning. The review includes a global panorama on the use of PHSP in the world, the technical and projective foundations on this type of technology, its benefits, and disadvantages, in addition to the new configurations and possible layouts for the construction of pumped hydro storage plants. Finally, the challenges and trends for the dissemination of PHSP technology are addressed.

“…Li et al [21] used seven-day hourly data to formulate a day-ahead optimization operation strategy for the PHS to maximize the economic benefits and similarity between the PHS generation curve and the load curve. Considering the uncertainty of PV, spot price, and load, Liu et al [22] proposed a sizing model of the hydro-PV-pumped storage according to economics and complementary index. Huang et al [23] proposed a day-ahead multiobjective stochastic optimal method for the CH-PV-PS system.…”

High photovoltaic penetration in a power system has significantly challenged its safety and economic operation. To use the complementary characteristics of various renewable energy sources (RESs) fully, a novel hierarchical scheduling control (HSC) method is presented to accommodate the variability and uncertainty of a cascade hydro-PV-pumped storage (CH-PV-PS) generation system. Considering the optimization functions and execution requirements of the CH-PV-PS system, the HSC method is divided into two layers: the dynamic optimization layer and the static optimization layer. The static optimization layer focuses on the economy of the CH-PV-PS system, and the dynamic optimization layer focuses on the safety of the CH-PV-PS system. In the first layer, that is, the static optimization layer, the objectives of the day-ahead and hour-ahead schedules are established, and a heuristic algorithm is combined with a linear programming algorithm to optimize the energy allocation. Considering the uncertainty of the PV power output and hour-ahead load, a real-time schedule is established in the second layer; that is, in the second layer, the dynamic optimization layer, real-time scheduling and prediction of active output are established. Model predictive control methods are introduced to correct for prediction bias at different time scales in order to fully utilize the control capability of hydropower generation. A CH-PV-PS real-world system in Southwest China is chosen as a case study. In the three scenarios, where only PV fluctuations are considered, the simulation results reveal that, compared with the traditional open-loop optimized and hierarchical open-loop optimization methods, the HSC method reduces the average relative deviation of PV and increases the system economics. After a large amount of RESs are connected to the power grid, the HSC method provides a solution for improving the consumption of RESs.

“…Numerous works published in recent years in international scientific journals confirm this. Hybrid systems with RES, such as [16], where the sizing of cooperating pumped hydro storage and PV generation units is described, and [17], where authors described an optimum size economic model of a wind powered pumped hydro storage system, showing the advantages of combining RES with energy storage. Apart from large pumped storage hydropower (PSH) systems, thermoelectric energy storage (TEES) is also used in the power system.…”

Multi Usage Applications of Li-Ion Battery Storage in a Large Photovoltaic Plant: A Practical Experience

The number of large energy storage units installed in the power system has increased over the last few years. This fact remains closely linked to the increase in the share of renewable energy in electricity generation. This is necessary to maintain the stability of the grid, which is becoming increasingly difficult to maintain due to the growing number of renewable energy sources (RES). Energy production from these sources is difficult to estimate, and possible unplanned shortages and surpluses in production are the cause of voltage and frequency fluctuations, which is an undesirable state. Consequently, the use of energy storage not only contributes to the regulation of grid operation but can also, under appropriate conditions, constitute an additional load if too much energy is generated by RES, or the source when the generation from RES is insufficient. The main contributions of this paper are as follows: A presentation of practical results achieved by implementing two optimal control strategies for a 1 MW (0.5 MWh) battery energy storage (BES) cooperating with a large 144 MW photovoltaic farm. In the first case, the BES was used to generate curtailment at photovoltaic farm to avoid power grid overload. The second case focuses on maximizing profits from selling the energy produced in periods when the unit price for energy was the highest according to energy market forecasts. In both cases, the storage was used simultaneously to cover the producer’s own demand, which eliminated the costs associated with the purchase of energy from the operator, especially during the night supply. A technical and economic evaluation was prepared for both cases, considering the real profits from the investment. The potential of using the BES to increase the functionality of photovoltaic energy sources was determined and discussed in the paper.
