A new voltage control scheme for active medium-voltage (MV) networks

Decentralized Voltage Control in Active Mv Distribution Networks

A decentralized voltage control strategy for MV distribution networks is here proposed, which is based on the possibility at any specific node to locally estimate the voltage level variations at the neighbouring nodes through the real-time measure of the current flowing on the incoming and outgoing lines. This enables to develop voltage control strategies accounting for 3 adjacent buses althoug...

Fuel Cell Voltage Control for Load Variations Using Neural Networks

In the near future the use of distributed generation systems will play a big role in the production ofelectrical energy. One of the most common types of DG technologies , fuel cells , which can be connectedto the national grid by power electronic converters or work alone Studies the dynamic behavior andstability of the power grid is of crucial importance. These studies need to know the exact mo...

Voltage and Reactive Power Control in MV Networks integrating MicroGrids

The main objective of this paper is to describe a strategy to deal with the voltage/reactive power problem for a MV distribution network integrating microgrids. The global problem, concerning all voltage levels, is detailed here and will imply the optimization of operating conditions by using the control capabilities of power electronic interfaces from DG sources, OLTCs and microgrids, through ...

A Coordinated Control Scheme for Improving Voltage Quality Using Power Electronics Interfaced DGs

Recently, increasing of non-linear loads in the power distribution network has been increased harmonics in these networks. The harmonics problems get worse and complicated by installation of power factor correction capacitors and filters. But the Distributed Generations (DGs) interface inverters with properly control can help to improve power quality, harmonic compensation and voltage unbalance...
