Design of Communication Network and Safety Protection Scheme for Virtual Power Plant

Virtual power plant aggregates flexible resources for regulation, which can improve the flexible regulation ability of the power system. However, with the development of virtual power plant, the scale and access mode of resources have changed significantly. The existing communication network and security protection schemes are not effective enough to support the safe and reliable access of large-scale heterogeneous resources. In this paper, the communication and security problems encountered by virtual power plant from the perspective of scheduling are sorted out. The communication network schemes of virtual power plant are designed to support multi time scale scheduling, the security schemes of virtual power plant that follows the power security protection specifications are designed. Finally, the key technologies for enhancing communication performance and security protection are proposed.
