A long-term analysis of pumped hydro storage to firm wind power

Energy storage systems for a low carbon future – in need of an integrated approach

“…Refs. [16][17][18] look at pumped hydro schemes, one considers technical enhancements in order to increase operational flexibility, the second looks at the business case in the long term, and the third at stand-alone power systemsall in anticipation of increased levels of intermittent renewable energy sources. Further, Ref.…”

Long-term chronological load modeling in power system studies with energy storage systems

“…Many of other studies utilize load duration curve (LDC) of planning horizon and approximate LDC into some desired levels [8,[24][25][26]. Since in the expansion planning problem, the goal of system planner is to determine the optimal size and location of generation plants and storage units, supplying the load demand of the network as well as sufficient charging and discharging of ESSs are of great importance [8].…”

A Multiobjective Robust Scheduling Optimization Mode for Multienergy Hybrid System Integrated by Wind Power, Solar Photovoltaic Power, and Pumped Storage Power

“…At the same time, in order to strengthen system safety and reliability and ensure system load to be guaranteed in poor water period, poor wind period, and low solar radiation period, CGT units can provide system reserve capacity in WPP and PV fluctuation time. In addition, CGT units can generate power to meet the load demand when the WPP, PV, and PS units cannot meet load demand [18]. The multienergy complementary operation integrated by WPP, PV, PHSP, and CGT units can both ensure the safe and reliable system operation and guarantee system load balance at the same time.…”
