EU-SysFlex blog: The EU-SysFlex French Industrial-Scale Demonstration: Coordinating Distributed Resources for Multi-Services Provision



Higher penetration of renewables will lead to new flexibility and ancillary services requirements to ensure the reliability of the power system. The provision of the system services such as frequency and voltage controls – so far mainly supplied by conventional synchronous units – would also be required for variable renewable generation connection or supplied by storage.

In previous studies and demonstrations worldwide, the ability of these new assets to provide individually system services has been investigated. However, the services provision may be restricted and intermittent by using single units’ abilities only, due notably to unfavorable wind/solar conditions or limited storage capacity. The performance and reliability of the procured services are therefore expected to be highly enhanced, from a local point of view, by aggregating renewable energy sources (RES) and storage abilities. Furthermore, cost-benefit analysis often shows that the revenues of a single service are not sufficient to cover the investment and operating costs. The provision of multiple services can help overcome this barrier thanks to additional revenue streams.

In this context, an aggregation approach based on the concept of Virtual Power Plant (VPP), allowing the aggregator to provide multiple services and flexibility products to the power system, was proposed in the Work Package (WP) 8 demonstration of EU-SysFlex project. The partners involved in this demonstration are EDF and ENERCON, with several of their branches and research teams cooperating for the needs of the demonstration work…read more
