Abstract
With the expansion of Renewable Energy Sources (RES) and due to their intermittency and lack of inertia, transmission system operators (TSO) are forced to procure larger power reserves to prepare for frequent and severe occurrences of imbalances in the future power systems. Hybrid Power Plant (HPP) which is a combination of technologies such as offshore wind power plant (WPP) and onshore solar power plant (SPP) connected with a Battery Energy Storage System (BESS) and Power-to-X (P2X) electrolysers can support the system by having a combined enhanced capability for the provision of frequency services compared to the individual RES. In this work, technical requirements for Fast Frequency Reserve (FFR), Frequency Containment Reserves (FCR) and Frequency Restoration Reserves (FRR) established in the Nordic Electrical system and applicable to the eastern part of Denmark, are summarized. Further, a centralised frequency control architecture based on frequency reserve allocation to HPP technologies by prioritization is proposed, which is implemented at the top-level control layer enabling coordinated response at the point of connection (POC). The simulation cases representing prequalification tests defined by TSOs demonstrate the performance of such architecture and highlight the capabilities of HPP to provide various frequency services while operating in different operation scenarios.
