Research on Energy Management and Hierarchical Optimization Control Strategy for Hybrid Electric Propulsion System
摘要
Abstract
To enhance the economic efficiency and dynamic performance of hybrid aircraft,an energy management strategy based on hybrid-powered hierarchical control is proposed.Firstly,at the upper layer,an energy manage-ment strategy based on the improved equivalent fuel consumption minimization is proposed,which dynamically ad-justs the optimal operating curve of the generator set based on its fuel consumption characteristics,the state of charge of the energy storage battery pack,and the equivalent penalty factor to achieve optimal fuel economy.At the lower layer,an improved droop control strategy incorporating current feedback is proposed.This strategy man-ages the charging and discharging states of the battery pack and maintains the dynamic balance of the DC bus voltage,thereby achieving cooperative control of economic efficiency and dynamic response.Consequently,it real-izes dynamic optimization management of the energy in hybrid electric propulsion vehicles.Finally,the effective-ness of this energy management strategy is validated through a hardware-in-the-loop experimental platform for hy-brid power systems based on RT-LAB.关键词
