Optimal Placement and Sizing of Distributed Generators Based on Swarm Moth Flame Optimization

In order to deal with the problem of environmental pollution and energy consumption, developing clean renewable maintain sustainable development society has become an urgent matter for human beings. Therefore, distributed generation (DG) is widely concerned by engineers. However, output DG generally random intermittent. When it connected different locations, capacities types power grids, safe stable operation system will be affected degrees. selecting optimal access scheme, grid planners must consider influence capacity, type location ensure a safer, more stable, reliable efficient operation. this paper proposes objective function considering integrated losses, voltage profile emission, swarm moth flame optimization algorithm (SMFO) used solve. Finally, based on IEEE-33 bus, effectiveness proposed verified.
