Energy storage system for wind power plant

Most significant drawbacks associated with renewable energy resources are intermittency and fluctuations. So they are not suitable for operating as base-load power station. Hybridization of two resources reduces this limitation but cannot eradicate it completely. An economic storage system with long duration power supply capability and durability can solve the problem. But most of the storage systems like pumped storage, super-conducting magnetic energy storage (SMES) etc. have their own limitations like large space requirement, higher cost, temperature dependence, etc. In this paper a spring storage system for a small wind power plant has been modeled and simulated which has potential to redress the major problems of the prevailing energy storage units of renewable power plants.
