The fuel cell system (FCS) is commonly combined with an energy storage (ESS) for enhancing the performance of ship. Consequently, battery ESS size and power allocation strategy are critical hybrid system. This paper focuses on designing a method to solve these two problems. First, degradation model employed assess lifetime. Subsequently, sizing problem optimal integrated into cost-minimization ...

A valve-controlled hydraulic cylinder system has the characteristics of uncertainty and time-variance, electro-hydraulic servo unit encounters shock, vibration, other external interference when working, which seriously affect stability system. Therefore, it is necessary to introduce an active disturbance rejection controller (ADRC) into control. However, there are many ADRC parameters, difficul...

To address the problem of diagnostic accuracy and stability degradation caused by random selection initial parameters for wavelet neural network (WNN) fault diagnosis model, this paper proposes a troubleshooting model based on improved gray wolf algorithm (IGWO) network. First, convergence factor policy weight update are redesigned in IGWO algorithm. This study uses nonlinear to balance global ...

This paper presents the optimal scheduling of active distribution network (ADN) with linear and non-linear loads in presence an integrated unit electric spring vehicle parking lot (IUEE). The proposed scheme is formulated form three-objective optimization, which minimizes expected operating cost ADN, voltage deviation function (VDF), total harmonic distortion (THD) separate objective functions....
