An Improved Particle Swarm Optimization Algorithm and Application in Available Transfer Capability

With electricity market reformation more deepening, available transfer capability is important public information for transaction participants in the deregulated power industry. Considering the calculation difficulties, the paper analyses the essence of ATC and the defects of existing solution methods, and a new improved particle swarm optimization model is established, the particle swarm optimization algorithm is introduced to reduce the computing time of settling the model which elevates the applicability of the particle swarm optimization algorithm and accelerates its convergence. At last, an improved dissipative operation model is constructed with the theory of dissipation which effectively overcomes the shortcoming of earliness.
