Research on Optimization Scheduling of Active Distribution Grid for planed Power Tracking of Interconnection Line

To enhance the comprehensive utilization of renewable energy and ensure the controllable stability of the main power grid, an active distribution grid system can be established to track and respond to the dispatching demands of the main grid. This paper proposes an economical dispatching strategy for the active distribution grid. This strategy aims to minimize the grid-connected running costs of the photovoltaic storage active distribution grid, considering the running status of photovoltaic module. It uses the hybrid BA-PSO optimization algorithm to solve the dispatching volume. By comparing with the power dispatching scheme without interconnection lines, the optimized dispatching strategy proposed in this paper significantly reduces the grid-connected running costs of the system while meeting the tracking of the main grid interconnection lines, even in the case of some photovoltaic module badly. This indicates that the dispatching strategy is feasible for the economical scheduling of the active distribution grid connected with main grid and can provide some application value for achieving economically reliable power supply.
