With the increasing emphasis on low-carbon energy development, reducing carbon emission in the energy production process has become a top priority. In recent years, low-carbon power generation technologies such as solar and wind power have made significant progress, gradually replacing traditional fossil-fuel-fired power generation methods. The large-scale integration of renewable energy into the grid has become mainstream, but the intermittent issues it poses to the power grid affect the stability of the power system. The rapid development of energy storage systems has become a bridge between renewable energy and the grid, providing flexibility and scheduling capabilities to the power system. In this study, we developed a communication platform based on the DNP3.0 communication protocol rules specified in Taiwan Power Company’s Enhanced Dynamic Regulation Reserve Service (E-dReg). The platform realizes multiple protocol conversions including DNP3.0, Modbus TCP, OPC DA, and VPN. Additionally, to enhance overall reliability, a redundant station startup mechanism based on transmission control protocol/internet protocol connection detection is proposed. This mechanism makes decisions based on the status of the master station, enabling redundant stations to rapidly start, automatically take over the master station, or determine whether to return authority to the master station. The results demonstrate that the communication platform can facilitate communication between Taiwan Power Company and users, ensuring the high reliability of the communication platform operation.
