With the continuous promotion of the construction of new power systems, the distribution system with the explosive growth of distributed photovoltaic and the emergence of plenty of flexible loads is undergoing profound changes. Regional multi-level power reverse transmission and jumping of power flow have become the new norma, which poses greater challenges to the operation of county power grids. Under the background of the construction of a new power system demonstration zone, this paper proposes a new paradigm of regulation and operation that integrates adjustable resource construction, panoramic perception of active distribution networks (ADC), and multi-level collaborative control to address the issue of high proportion and large-scale activeness in distribution networks. Relying on the intelligent terminals and deployment integrated management and control platform in station area, the sensing and adjustment capabilities of the active distribution network have been enhanced, the on-site consumption of distributed photovoltaics has been promoted.
