1results about How to "Reduce curtailment" patented technology

This invention discloses a forward-looking section over-limit control method and system for transmission-distribution networks incorporating renewable energy. The control method comprises the following steps: obtaining the predicted renewable energy output data using existing data-driven distributed photovoltaic cluster output prediction methods; assuming full renewable energy generation, constructing a scenario where renewable energy is fully connected to the grid; using the Matpower tool to perform power flow calculations to determine the predicted section over-limit situation; establishing a forward-looking section over-limit control model and determining the objective function and constraints, the objective function being to minimize the sum of curtailment cost and over-limit penalty cost; using a CPLEX solver to solve the objective function in a rolling manner over time periods, deriving the optimized photovoltaic curtailment plan and energy storage charging and discharging strategy; and issuing power adjustment commands. This invention, by establishing a multi-time period optimization model, coordinates photovoltaic curtailment and energy storage charging and discharging, significantly reducing the risk of section over-limit, improving grid security, and increasing renewable energy utilization.
