(PDF) Optimization of hybrid PV/wind power system for
Among the various renewable resources, hybrid solar and wind energy seems to be promising solutions to provide reliable power supply with improved system efficiency and
Thus, the goal of this report is to promote understanding of the technologies involved in wind-storage hybrid systems and to determine the optimal strategies for integrating these technologies into a distributed system that provides primary energy as well as grid support services.
Co-locating energy storage with a wind power plant allows the uncertain, time-varying electric power output from wind turbines to be smoothed out, enabling reliable, dispatchable energy for local loads to the local microgrid or the larger grid.
To expand on the grid support capabilities of wind-storage hybrids, GE conducted a study on wind power plants with integrated storage on each turbine rather than central storage, along with an extra inverter and transformer for redundancy (Miller 2014). There are always some trade-offs involved in choosing a storage topology.
Regarding flexibility, hybrid wind systems can provide: Ramping up or down to support the increase in the frequency and severity of ramping events in the grid related to increasing variable renewable contributions.
