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 s...

In this paper, using particle swarm optimization (PSO) based method is developed to determine the optimal allocation of distributed generators (DGS) on a multi phased unbalanced distribution network. PSO algorithm has been programmed in MATLAB using open source software called OpenDSS in a cosimulation environment to solve the unbalanced three-phase optimal power flow (TOPF) and to find the opt...

Faults in medium and high voltage grids lead to voltage sags in the low voltage level. Due to the voltage dip, distributed generators disconnect from the low voltage grid. Depending on the amount of disconnected generation, system stability could be compromised. With a dynamic grid support, distributed generators remain connected to the grid during faults, also called fault ride-through. Moreov...
