New strategies for coordinated control in power distribution grids — Effective integration of photovoltaic plants utilizing sensitivity analysis

This investigation aims at providing recommendations to distribution system operators on how to effectively integrate photovoltaic plants in the distribution network. The focus is laid on utilizing the sensitivity analysis to coordinate voltage control and optimize the total reactive power required. Furthermore novel strategies are introduced for an effective use of the reactive power capability of PV plants. The main goal is to pave the way for system operators to use PV plants for operation management purposes by means of integrating them in their SCADA system.
