Full-Stack Development Process for Demand Side Flexibility Solutions from Cyber-Physical Testbeds to Field Operation

The ongoing energy transition necessitates a comprehensive transformation of the electricity supply system. This presents grid operators and utilities with the challenge of maintaining stable and reliable grid operation in the presence of a large number of variable renewable energy sources. Demand-side management solutions, especially for behind-the-meter assets, will play a crucial role in future grid concepts by providing demand-side response to support system stability. These solutions often rely on centralized or decentralized platforms that operate outside of the supervisory control and data acquisition systems currently used by distribution system operators. To effectively utilize the operational flexibility offered by demand-side management solutions in real-world settings, several technical domains must be addressed, including power systems, information and communication technology, and operational processes. This paper outlines the steps taken to develop and analyze demand-side management solutions, including the simulation of operational processes, testing in a smart grid laboratory, and field tests with real-world customers.
