Bus Voltage

In the direct current (DC) microgrid composed of multiple distributed generations, due to the different distances between various converters and the DC bus in the system, the difference of the line resistance will reduce the current sharing accuracy of the system. The droop control was widely used in the operation control of the DC microgrid. It was necessary to select a large droop coefficient to improve the current sharing accuracy, but a too large droop coefficient will lead to a serious bus voltage drop and affect the power quality. In view of the contradiction between the voltage regulation and load current sharing in the traditional droop control, a hierarchical control algorithm based on the improved droop control of the fuzzy logic was proposed in this paper. By improving the droop curve, the problems of voltage regulation and current sharing were solved simultaneously. The effectiveness of the algorithm was verified by simulation.

Iec 61499

When creating distributed control systems, we can choose one of two possible approaches based on IEC 61131 and IEC 61499 standards. The first of them has been used for a long time in the PLC sphere, but it does not directly support the creation of extensive distributed systems. The second of the standards, IEC 61499, offers a direct solution for distributed system creation. The truth is that it is a new standard, which is why it is supported by only a few device manufacturers. This raises the question of which approach and which standard is more effective and suitable for individual system designing.
