Embodiment Construction

[0033] The preferred embodiments are described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0034] Step 1: Establish a line construction planning model aiming at the minimum investment cost.

[0035] Step 2: Solve the first-stage model with a two-layer multi-objective optimization genetic algorithm.

[0036] Step 3: Use improved coding method and genetic operator to ensure the feasibility of the solution.

[0037] Step 4: Adopt the optimal individual retention strategy, and directly enter the individual with the best fitness value in the current generation into the next generation without participating in crossover and mutation operations. Random league selection combined with optimal individual retention is chosen as the final selection method.

[0038] Step 5: Use a small crossover rate and mutation rate in the initial stage of iteration to ensure the l...

Abstract

The invention discloses a high voltage distribution network optimizing and scheduling method. The method is characterized in that with the comprehensive optimization of the power supply capacity, the circuit establishment and the partition and contact mode as the target, a two-stage high voltage distribution network optimizing and scheduling model is established. The method is used for scheduling the 220 kV power supply point position and capacity, scheduling circuits with voltage of 110 kV or lower and comprehensively optimizing the load optimizing partition and contact scheme.

Description

technical field [0001] The invention belongs to the field of power grid optimization planning, and in particular relates to a high-voltage distribution network optimization planning method. Background technique [0002] In the urban power grid, the high-voltage distribution network is an important link connecting the transmission network and the medium-voltage distribution network. While receiving the electric energy sent by the 220kV substation, it is used as a power source to further transmit the electric energy to the 10kV switching station or distribution transformer near the load center. , and its planning results will affect the overall economy and reliability of the urban power supply and distribution system. However, there is currently a lack of coordination between high-voltage distribution network planning and transmission network planning, and the planning models and methods are not refined enough. [0003] Aiming at this problem, the present invention proposes a...
