PO384: Optimizing Storage Sizing for System-Level Value in Hybrid Offshore Wind Plants
Sander des Tombes, Public & Regulatory Affairs, DMEC
Abstract
The development of offshore wind faces growing challenges, including price erosion and grid congestion. Storage systems offer a potential solution by addressing the spatial and temporal mismatch between supply and demand across multiple time scales. Moreover, the limited availability of grid connection points increasingly encourages the co-location of storage assets with renewable generation. Most studies on co-location between storage assets and wind farms focus on revenue maximization by focusing on a given electricity market. However, storage systems can participate in multiple electricity markets. Results obtained are therefore highly related to the participation market chosen and to market conditions that are specific to the year chosen for the study. In the present study, the investigation centers the system value that storage assets can add to co-located wind farms. Assuming techno-economic specifications for different storage technologies, this study investigates the minimal storage capacity required to meet key system-level operational requirements at the wind plant level. We present various operational requirements alongside key cost-effectiveness metrics, highlighting how the integration of storage can improve performance relative to a baseline wind plant, such as the Levelized Cost of exported Energy. We then parametrize an optimal control problem based on a high-level quasi steady representation of an energy storage system. Non-linear optimization solving techniques are used to find the energy storage control strategy that matches the operational requirement with the minimum installed storage size or cost, for a given time series of offshore wind production. Various curtailment scenarios such as avian curtailment or grid congestion curtailment are accounted for as extra constraints and their impact is discussed. Rather than minimizing curtailment, we focus our result on minimizing the deviation between the exported power and a general demand curve synthetically accounted for based on literature inputs.
