PROJECT TITLE :

Multi-level dispatch control architecture for power systems with demand-side resources

ABSTRACT:

Demand-aspect resources have considerable potential, which can offer economical load shedding operations therefore as to take care of the supply–demand balance along with generating units. This study is worried with active power dispatch and management problems by considering both generating units and demand-side resources, where some controllable masses in demand-facet are aggregated beneath each bus load agent. A multi-level dispatch control architecture is proposed, that can handle the optimisation and management problems in numerous time scales. Specifically, an upper layer performs calculation of system's look-ahead dispatch for generating units and bus load agents, whereas a middle level computes management actions for multiple load clusters in each bus load agent via a distributed consensus estimation algorithm, and multiple energy management units in the lower layer respond the control instruction issued from the load cluster based mostly on a distributed pinning management algorithm. For the middle and lower layers, participants will communicate with its neighbours via sparse communication networks for the sake of distributed calculation or distributed management, which is additional strong than the centralised strategies in terms of dealing with massive amounts of participation units. The simulation results on a changed IEEE 9 bus system show the applicability of the proposed design.
