Abstract


Transmission expansion planning is an important part of the planning of the power system , it is important work to safeguard the sustainable development of the power industry . Scientific and rational implementation of transmission expansion planning can maximize conservation of national infrastructure investment , improve the national economic and social benefits . This is the first study swarm coevolution food chain eco- evolutionary algorithm EEAFC (Ecology Evolutionary Algorithm of Food Chain) applied to the transmission grid expansion planning . Fully consider the to lose network expansion planning multi-dimensional, multi-constrained , nonconvex , nonlinear characteristics analysis to discuss the food chain eco - evolutionary algorithm applied to the output characteristics of the network expansion planning , combined with other artificial intelligence algorithms ( such as genetic algorithms, simulated annealing algorithm ) the advantages of the food chain eco- evolutionary algorithm is used to lose five network expansion planning improvement ideas : 1 ) vertical search mechanism introduced multi- population genetic operation strategy ; 2 ) memory representation of special local optimum population \set the proper evolution of the initial chain ; 4 ) the introduction of a secure border search strategy ; 5 ) hybrid algorithm . The food chain eco - evolutionary algorithm is introduced into the field of power transmission network expansion planning , static expansion planning and dynamic expansion planning to commence a study on the grid respectively . Example simulation results show that the eco - evolutionary algorithm based on the food chain improvements can be effectively applied to the transmission expansion planning , and has better convergence speed and global convergence , eco - evolutionary algorithm for the food chain in the transmission grid planning to lay a good foundation .
