The increasing penetration of renewables at TSO and DSO level, requires more complex solutions for ancillary services. Currently, in large interconnected power systems, there are various solutions for their calculation. The ancillary services for load balancing control or for cross-border power exchange are currently calculated based on SCADA measurements or on TSO's AGC order. In this paper authors propose alternative solutions for calculating, with high accuracy, the ancillary services and quality of service by using legally enforced metrology meters using 1-minute load profiles. These solutions are based on several exploratory tests performed within the Romanian power system and on various simulations. Moreover, the traded quantities on energy and balancing markets can be exactly retrieved on the metrology meter measurement — trustable through IEC accuracy compliance, thus bringing high transparency and trust for partners. The method applies also for aggregated services provided e.g. by Virtual Power Plants. |
