Ancillary services to grids provided with distributed generation

摘要

The paper introduces system for utilization of the customer-side generated energy. Additionally system can secure some ancillary services to grids. Those services include: current active filtering, load voltage stabilization and in case of grid voltage faults - uninterruptible load supplying (possible with energy storage device). Presented experimental results confirm flexibility of this arrangement in processes of power delivery improvement. Additionally on the base presented solution a multilane DGs/EPS interface system is presented. Multilane arrangement posses all the properties of the single line, together with capabilities for active power exchange between lines.
