Optimized voltage control in autonomously controlled networks

The increase of distributed generation has strong impact on network operation and design. Local equilibrium of load and generation in combination with implementing power electronics and storage opens the possibility for autonomously operating networks. These networks operate in cooperation with the total electric grid, resulting in manageable networks. Intelligent control activities result in better network performance like controllable flat MV voltage profiles. Due to this relatively flat voltage profile over the whole MV network it becomes possible to obtain an optimal voltage level at the LV customer based on actual loads and generation. This significantly reduces voltage variations in the LV network caused by fluctuations in load and generation and improves voltage quality for LV customers
