Robust and Scalable Management of Power Networks in Dual-Source Trolleybus Systems: A Consensus Control Framework

PROJECT TITLE :

Robust and Scalable Management of Power Networks in Dual-Source Trolleybus Systems: A Consensus Control Framework

ABSTRACT:

Twin-source trolleybuses powered by onboard battery and grid electricity offer unique benefits in fuel economy, value reduction, and passenger capability, that are particularly appealing for public transportation in populated cities. Their mobility and power offer network configurations introduce difficult power management problems on their dedicated offer power grids. To make sure safe, reliable, and efficient operation of trolleybuses, their high-current and dynamic loads should be distributed to the feeders properly and promptly. Primarily based on bound rising networks of feeders and provide stations for town trolleybus systems, this paper introduces a brand new framework for current flow balancing based on recently developed weighted-and-constrained consensus control strategies to manage the power offer network. Using solely neighborhood information exchange among feeder lines in the network, the consensus control can achieve international current balancing with fast convergence to a balanced state, robustness to load perturbations, reconfiguration with feeder addition and deletion, and rebalancing under feeder capability variation. The methodology is scalable in the way that system expansion can not substantially increase the management system complexity. The ability system configurations of the Beijing dual-source trolleybus system are used for simulation case studies on the new power management methods. Robustness and scalability are demonstrated, together with discussions on the feasibility, flexibility, and implementation problems of the methodology.
