Grid integration of multiple flywheel energy storage systems

该项目将着眼于优化电网应用中多飞轮储能系统的效率、疲劳寿命和成本。能源系统运营商/所有者需要储能来稳定电网，以应对电力需求和供应的波动。当将可再生能源纳入孤岛、偏远或“薄弱”的微电网时，这一点尤其重要。威廉姆斯已经开发完善的创新飞轮储能技术非常适合这种应用，因为其响应速度快、功率高、维护成本低，并且使用寿命长达20年。通过该项目，将开发可扩展的多飞轮系统的监督控制策略，以优化系统效率和飞轮疲劳寿命。还将研究在效率和成本方面的最佳并网逆变器布置（数量和额定值），以进一步改进完整的储能解决方案。

The project will look at optimising efficiency, fatigue life, and cost of multiple-flywheel energy storage systems for grid applications.Energy system operators/owners have a need for energy-storage in order to stabilise grids against fluctuating power demand and supply. This is particularly relevant when incorporating renewable energy sources into islanded, remote or 'weak' micro grids. Williams' already well developed and innovative flywheel energy-storage technology is ideally suited to this application, due to its fast response, high power, low maintenance, and twenty year life. Through this project, supervisory control strategies for a scalable multiple flywheel syetm will be developed to optimise system efficiency and flywheel fatigue life. Optimal grid tie inverter arrangements (numbers and ratings), in terms of efficiency and cost, will also be investigated to further improve the complete energy storage solution.
