Economic Benefit Analysis of an Energy Storage Station Supporting Renewable Energy Stations towards New-Type Power Systems

This research looks at how to measure the economic benefits and find the best joint operation of energy‑storage stations that work together with renewable power sources in today’s grids. As more wind, solar, and other renewables are added, keeping supply and demand balanced gets harder. The project builds a framework that evaluates capacity benefits by simulating both power production and system operation. It creates a joint‑optimization model that includes wind, solar, hydro, thermal generators, and energy‑storage units. By running a simulation of a local grid’s day‑to‑day behavior, the method shows how storage can lower the amount of conventional thermal capacity that must be built and how it can cut back

on renewable curtailment. The work also gives clear steps for: – modeling power systems with many sources, – setting up objective functions that minimize operating costs, and – checking whether investing in storage makes economic sense. With the tools provided, students can study how the size and placement of storage affect system reliability and the amount of curtailed renewable energy. This creates a solid basis for making policy and investment choices in modern power systems.
