Abstract

An integrated power converter and battery energy storage system (BESS) has been proposed to meet multi-functional requirements for active and reactive power control and harmonic filtering in large wind power plants (WPPs).
In this paper, first a high-voltage, high MVA static synchronous compensator (STATCOM) based on modular multilevel converters (MMCs) with an integrated BESS system is analyzed from the techno-economic feasibility point of view. Economic benefits of the additional functionalities are quantified based on available market data (and trends) for ancillary services or the least cost option for the mandatory compliance with the relevant Grid Code. Afterwards, its efficacy in achieving different ancillary services to the WPP and to the grid is qualitatively discussed. Their significance to the operation and control of offshore WPPs and their relevance for the market and the grid are evaluated.
