Flexible balancing power services within four control zones, using e-trading platform - Future Flow project

摘要

Four European TSOs of Central-Eastern Europe (Austria, Hungary, Romania, Slovenia), associated with power system experts, electricity retailers, IT providers and renewable electricity providers, designed unique regional cooperation scheme, aimed at opening Balancing and Redispatching markets to new sources of flexibility and supporting such sources to act on such markets competitively. By means of a prototype aggregation solution and renewable generation forecasting techniques, flexibility providers - distributed generators (DG) and commercial and industrial consumers (C&I) providing demand response (DR) - are enabled to provide competitive offers for automatic Frequency Restoration Reserves (aFRR). A comprehensive technical-economic model for the cross border integration of such services involves a common activation function (CAF) tailored to deal with congested borders, with limited Cross-zonal Capacity (CZC). The resulting CAF is implemented as a Cloud solution of Regional aFRR Balancing energy Platform. This paper aims to present the current state of aFRR approaches in Austria, Hungary, Slovenia and Romania as well as the selection of target model for aFRR energy exchange verified within the research and innovation project Future Flow. Furthermore, the application of various CZC constraints is presented. The final part contains conclusions and recommendations for the future development and deployment of pilot tests.
