A Multi-stage Expansion Planning Method for Distribution Networks Based on Explicit Reliability Index

Blog Article

Modern distribution networks are often constructed in grid and operated in a radial manner to improve the transfer capacity under fault conditions.The traditional distribution network planning method generally adopts the two-stage iterative calculation method of planning design and reliability evaluation, which can only obtain an extensive planning scheme; the resulting planning scheme is either over invested or unable to meet Ironing Mat specific reliability requirements.Therefore, a multi-stage distribution network expansion planning method considering reliability constraints is proposed.

The reliability index calculation process is AC/DC Adaptor Plug analyzed and embedded into the planning model, which can accurately consider the fault isolation, load transfer and recovery strategies.Based on the linearized power flow, the planning model is a typical mixed integer linear optimization problem, which can be effectively solved.The performance of the proposed method is verified in the Portugal 54-node system.

The simulation result proves the effectiveness and flexibility of this method.
