The global acceleration of Energy Storage (ES) Systems integration, including batteries and supercapacitors, is transforming power systems. This brochure offers valuable insights into converter topologies, modeling, and the benefits and challenges of integrating ES in HVDC and STATCOM systems.

The rise of HVDC installations and power system decarbonization necessitates integrating storage systems. This paper explores the feasibility of connecting storage on the DC side of HVDC systems to provide three ancillary services: power oscillation damping (POD), fast frequency response (FFR), and wind power oscillation smoothing. A design methodology is proposed and validated through simulations, confirming the system's ability to deliver these services and proving its technical feasibility.

Power converters are essential for renewable energy integration, and this study uses Life Cycle Assessment to evaluate the environmental impact of a DC Solid State Transformer. The use phase generates the most emissions, which will decrease as electricity decarbonizes. An optimal operating frequency is identified by factoring in carbon tax, with future economic costs of emissions expected to rise.
