RESEARCH ON POWER COORDINATION CONTROL OPTIMIZATION STRATEGY OF HYBRID ENERGY STORAGE ARRAY SYSTEMS BASED ON EVENT TRIGGERING

When the power coordination control strategy of the Hybrid Energy Storage Array System (HESAS) adopts time triggering, the communication of information between the upper layer and lower layer will continue based on a fixed cycle. The communication resources have been constantly occupied, which has put some pressure on communication. To solve the above problems, this paper proposes an optimization strategy based on event triggered control. When the system is in a steady state, the controller does not need to frequently update the control signal, and the system can still operate stably. Therefore, event triggered control is added to the feedback communication from the lower layer control to the upper layer control, which can reduce the feedback communication volume and alleviate the communication pressure of the hierarchical control system. Finally, the effectiveness of the proposed strategy is verified through simulation.
