Dynamic reactive power and energy storage for integrating intermittent renewable energy

The role and application of energy storage and dynamic reactive power support is discussed in this paper. A well-engineered energy storage plant can help alleviate some of the problems encountered with the integration of intermittent renewable resources and at the same time make renewable power plants more cost effective in existing traditional power system. The intent of this paper is to demonstrate these features by means of a planned application of a STATCOM and Battery Energy Storage System (BESS) in a region with high penetration levels of wind and solar integration. Firstly, the paper describes the integration challenges of integrating intermittent renewable energy, followed by possible mitigation measures. Thirdly, a specific application of a STATCOM with a BESS is included and the different possible revenue streams are calculated.
