Cooperative Power Conditioners for Microgrids in Mining

This paper proposes a cooperative control scheme for power quality compensation, exploiting the remaining capacity of power electronics converters typically used in microgrids for active power supply. Consensus terms are proposed to mitigate imbalances and harmonics in a mining-industry microgrid. In contrast to the classical approach, cooperative power compensation uses not only information from local loads, but also information from neighboring compensators and power sources. Simulations show that the proposed cooperative scheme reduces the unwanted power components similarly than the classical approach, but also turns the system robust to communication network changes and converters saturation.
