This study presents a hierarchical distributed structure based on the Holonic concept for reactive power control in smart grids. Holons, as the main parts of the proposed framework, are able to negotiate together, change their boundaries, and alter the role of their members. These abilities improve the flexibility and performance of the novel structure in order to adapt itself to different situations. The proposed methodology is successfully scrutinised through different case studies based on a transmission test system connected to seven distribution networks. The new method is compared with two structures using a set of evaluation indices. The simulation results have revealed that improving the computational efficiency, minimising the active power losses and voltage deviations, optimal utilisation of reactive power sources, less data traffic loads, and increasing the fault tolerance are some key features of the proposed approach.

In order to effectively use of water resources and improve control problem of hydropower station gate, we can use the field bus technology, Ethernet technology, PLC technology, etc. In this paper, we studies a kind of new distributed network structure hydropower station gate control system. The gate can realize insect control and remote monitoring, effectively improve the monitoring and real-time ability and work efficiency. The system is of high reliability and high transmission speed, low cost, convenient use and maintenance etc.
