Abstract

The invention provides a power transmission network capacity planning optimization method and system considering multiple fault scenes, and the method comprises the steps: taking the minimum annual comprehensive cost as an optimization target, and constructing a power transmission network robust random optimization planning model considering the multiple fault scenes and the uncertainty of the fault probability; introducing a state variable and related constraints of load shedding punishment generated by a multi-device fault scene into the power transmission network planning model to obtain apower transmission network planning robust optimization model meeting various constraint conditions; the uncertainty part in the constraint condition is determined; and converting a power transmissionnetwork into a double-layer optimization model through duality, solving a subproblem through duality, and finally solving a power transmission network robust stochastic optimization planning model considering multiple fault scenes and fault probability uncertainty by adopting a Benders decomposition algorithm and a mixed integer linear programming algorithm to obtain a planning scheme of the power transmission network.

Description

technical field [0001] The disclosure belongs to the field of power system transmission network planning, and relates to a transmission network capacity planning optimization method and system considering multiple fault scenarios. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Transmission network planning is one of the basic contents of power system planning. Power network planning that takes into account both effectiveness and economy can not only ensure the balance of power supply and demand and the safe operation of the system, but also save certain construction costs for power companies, which is in line with the development of the power market. need. The main goal of transmission network capacity planning is to determine how much transmission capacity to expand in the planned level year and where to meet the increasing demand of l...
