Transmission Network Optimal Planning Based On Plant Growthsimulation Algorithm

摘要

A new method, which employs a plant growth simulation algorithm (PGSA) as optimal means, is presented in this paper for solving the optimal planning problem of a transmission network in a single stage (horizon year). The transmission network planning is formulated as an integer programming problem subjected to the constraints such as overload, N - 1 security, and right-of-way, and an efficient solving approach based upon PGSA is developed. PGSA is a new and highly efficient random search algorithm, which characterizes the growth process of plant phototropism and can quickly find high quality solutions of the combinatorial optimization problems. The test results for two systems have verified the feasibility and efficiency of the developed PGSA based transmission network optimal planning method.
