Customer ServiceThe case study utilised a self-integrated reservoir for wave energy storage, using a simple control that was following the load. The extra cost incurred due to the battery which was considered as a capital expenditure (CAPEX). Operational expenditure (OPEX) included the battery replacement if required. The revenue stemmed from savings in electricity fees
Customer ServiceThe volume of the reservoirs will determine the overall capacity of the plant to store and supply energy. The more water, the more energy it can contain. However, for a given storage capacity, the output will depend both on the size of the turbines and the head. A high head can deliver more power from a given flow of water than a small head.
Storage hydropower plants include a dam and a reservoir to impound water, which is stored and released later when needed. Water stored in reservoirs provides flexibility to generate electricity on demand and reduces dependence on the variability of inflow.
The construction of pumped storage power stations among cascade reservoirs is a feasible way to expand the flexible resources of the multi-energy complementary clean energy base. However, this way makes the hydraulic and electrical connections of the upper and lower reservoirs more complicated, which brings more uncertainty to the power generation.
Storage in hydropower reservoirs is important to the management of both water resources and the electric grid, especially with variable water availability and evolving grid needs.
