This paper presents a novel method of capturing more energy from the wind using short-term energy storage in a hydrostatic wind turbine. A hydrostatic transmission (HST) not only provides reliable operation but also enables energy management features like energy regeneration using hydraulic accumulators. In this study, turbulence-induced wind transients occurring near the rated power are exploited to extract more energy from the wind. Wind characteristics are analyzed to develop models to quantify the energy losses due to the wind turbulence and the potential energy gains from the short-term energy storage. A dynamic simulation model of the hydrostatic wind turbine and the proposed energy storage system is developed. A rule-based control strategy for the energy storage is proposed. Results show that in a 50 kW hydrostatic wind turbine, the annual energy production (AEP) can be increased by 4.1% with a 60 liter hydraulic accumulator.

Since renewable power is intermittent and uncertain, modern grid systems need to be more elegant to provide a reliable, affordable, and sustainable power supply. This paper introduces a robust optimal planning strategy to find the location and the size of an energy storage system (ESS) and feeders. It aims to accommodate the wind power energy integration to serve the future demand growth under uncertainties. The methodology was tested in the IEEE RTS-96 system and the simulation results demonstrate the effectiveness of the proposed optimal sizing strategy. The findings validate the improvements in the power system reliability and flexibility.
