Integration of Power-to-Gas Conversion into Dutch Electrical Ancillary Services Markets

This paper investigates the viability of the integration of demand side response of large scale electrolyser facilities into electrical ancillary services markets. A review of the current structure and mechanisms of balancing markets, voltage control and congestion management in the Netherlands is presented, taking into consideration future market harmonization measures proposed by transmission system operators of central Europe. The conducted research includes the assessment of the technical adequacy of electrolysers with respect to existing prequalification requirements, as well as basic notions on the expected revenue from participation in these markets. Furthermore, to illustrate the value of electrolyser support for electrical networks, a case study derived from the predicted Groningen-Drenthe-Overijssel area for the year 2030 is developed. This section of the northern Dutch transmission grid includes the upcoming HVDC interconnection with Denmark (COBRAcable) and one of the largest offshore wind parks located in the North Sea (Gemini). Computer based simulations are performed with DIgSILENT PowerFactory. The obtained results highlight the potential benefits of electrolyser utilization
