According to Table 5, it was observed that the average daily electrical energy consumed to charge the water tower based energy storage system is equal to 3.78 (MWh). The amount of electrical energy generated in the discharge stage is calculated using Eq. (53) as 2.415 (MWh).
In the last part of the research, an energy storage system was designed to store the generated electrical energy. For this purpose, an energy storage system based on water pumping in water towers was designed. Water towers with different classes were investigated.
In order to design the water tower required for energy storage, in the first case, the height of the tower tank is considered to be 5 (m). As a result, according to Eq. (50), the height of the tower will be 30 (m). Considering the radius of the tank equal to 4 (m), the cross-sectional area of the tank is about 50 (m 2).
Also, the energy used to pump water to the tower is equal to 26,229 (kWh). Therefore, the energy conversion efficiency of the water tower is equal to 70.94 %, and the efficiency of the entire energy recovery and storage system, which consists entirely of small towers, is 64.04 %. The required number of small water towers is calculated as 144.
The highly variable power generated from a battery energy storage system (BESS)–photovoltaic distributed generation (PVDG) causes harmonic distortions in distribution systems (DSs) due to the intermittent nature of solar energy and high voltage rises or falls in the BESS.
