Event-Triggered Consensus Control of P2HH-Based Integrated Energy Systems with Two-Time Scales
Abstract: In this paper, an event-triggered consensus control
strategy is designed to realize the consensus of a Power to
Heat and Hydrogen (P2HH)-based integrated energy system
with two-time scales. The coupling of different energy sources
and the characteristics of multi-time scales in the P2HH-based
integrated energy system may cause instability or inefficiency in
the control process. To solve this problem, first, using the singular
perturbation theory, the two-time scales system is decoupled
into the fast and slow dynamics to find the control gain. Then,
an event-triggered mechanism is proposed to independently
determine the information transfer moments for the slow and fast
dynamics of the system. Meanwhile, the P2HH-based integrated
energy system is mathematically modeled. In order to achieve the
consensus of indoor temperature and generator angular velocity,
the designed consensus protocol is applied to the P2HH-based
integrated energy system. It is demonstrated that the designed
protocol can realize the consensus of the P2HH-based integrated
energy system. Finally, simulations validate the designed control
strategy, even if the topology is changed.
