| 英文摘要 |
| The economic operation of the microgrid is a continuous optimization problem with multi-constraints, it
not only optimizes each power resource to achieve the optimal condition, but also coordinates various power resources to
satisfy the power constraint between the supplement and demand in different periods. A hybrid particle swarm optimization
algorithm is proposed in this paper which is based on the stochastic weight trade-off particle swarm optimization algorithm,
the immune mechanism is introduced to uniformly distribute particles in the coordinate plane. Furthermore, the nonlinear
weight is integrated to improve the searching ability and the sub-gradient method is presented to accelerate the convergence
rate. Each controllable power resource is deployed dynamically. The electricity market mechanism is added into the
microgrid system to dispatch power resources with more effective and to achieve the economic benefits. The simulation
results of the island and grid-connected operation modes show the effectiveness and validity of the proposed algorithm. |
