Investigating the potential of electrical energy storage in combination with wind farms, Laborelec developed a first simulator for storage sizing and profit quantification

It is today still difficult to make an accurate day-ahead forecasting of the energy that will be produced by a wind farm. To couple energy storage systems to large wind farms can solve most of the problems related to this unpredictability [1]. Laborelec developed a simulation tool called Wind Storage Simulator (WSS) in order to quantify what would be the profit and to make a pre-sizing of the storage system for different scenarios. These scenarios can be to reduce the unbalance between nomination (forecast power) and actual production, to reduce the lost energy due to grid congestion, to optimize the production on the electricity spot market or to contribute to grid service systems. This tool is based on real characteristics of storage technologies, on real historical wind farm production profiles and on real data of the grid codes and electricity markets.
