“…where I i is a currents vector of element i, pI i is a currents derivative vector of element i, U i is the vector of voltages applied at the terminals of the element i, A i and B i are matrices whose dimension depends on the coordinate system in which the structural element is modeled, as well as on whether these equations are complete or simplified, and H i is the vector of impact on the element i [15]. The main models of elements in the transformed coordinates d and q of the PSS are shown (the generally accepted notations are used when writing systems of mathematical description):…”

“…In addition, the CTS-O with two power transformers of 1600 kVA is connected to the GTPS "Ilyichevskaya" (by cells 2 and 15), which includes the loads of the booster compressor modules (BCM) and the low-voltage loads of the GTPS units themselves. Furthermore, the GTPS "Ilyichevskaya" GPP provides the power supply to the oilfield and nearby settlement loads connected to the 10 kV busbar of the SS 35 kV "Ilyichevskaya" (Scheme 2) [15]. switchgear units 13, 14, and 16, accordingly.…”

The problem of the quality of electric energy in the utilization of petroleum gas is considered. The article presents the results of the development of a mathematical description of power supply systems with gas turbine power stations based on two-shaft gas turbine units. The typical power distribution scheme of a gas turbine power station is given. The joint analysis of the generation modes of the gas turbine power station and the detected deviations of the power quality indicators values was carried out. The influence of the used mode on the power quality indicators is determined. As a result, the factors of operation of a gas turbine power station that affects power quality are identified, and recommendations for their elimination are given.

“…There are two ways in which distributed generation can be performed: it can work separately or in parallel with any existing centralized power supply system. The latter method for ensuring uninterruptible power supply is more widespread and can be called a hybrid power supply system or a grid-connected renewable energy system [3], [6]. In addition, in many countries, conventional centralized or public power supply systems are very old and unreliable but they cannot be replaced immediately by distributed generation [7].…”

The paper presents the results of a study on hybrid filter operation and performance under hybrid power supply. In the study, a hybrid filter structure was developed and proved to perform a set of power quality improving functions. The paper demonstrates that it is necessary for the hybrid filter structure to be variable in order to adapt to changes in power supply. A case is made for using an additional passive filter at the active part output of the hybrid filter under distributed generation. The optimal structure and parameters of such an additional passive filter are identified and proved. Based on the experimental research results, the mathematical and computer simulation models of the proposed hybrid filter for hybrid power supply were developed. The modeling and simulation results showed the efficiency level to be satisfactory and power quality to improve due to applying the proposed hybrid filter. Using the modeling and simulation results, an adaptive algorithm to control the operation factors of the proposed hybrid filter under hybrid power supply was developed, tested, and evaluated. Practical recommendations for industrial application of the proposed hybrid filter are given.

“…Because of the success of hybrid-electric solution on conventional vehicles, piston engine is usually adopted in HPUs. In fact, turboshaft engine has higher power to weight ratio in comparison to piston engine, especially when it concerns high power requirement, and these advantages make the turboshaft engine have preferable performance in HPU [9]. ere are lots of obvious differences including but not limited to structure and aerospace features between the turboshaft engine and the piston engine, therefore the investigation on HPU with turboshaft engine is worth exploring for better performance of aerial vehicles [10].…”

In recent years, the green aviation technology draws more attention, and more hybrid power units have been applied to the aerial vehicles. To achieve the high performance and long lifetime of components during varied working conditions, the effective regulation of the energy management is necessary for the vehicles with hybrid power unit (HPU). In this paper, power prediction-based model predictive control (P2MPC) for energy management strategy (EMS) is proposed for the vehicle equipped with HPU based on turboshaft engine in order to maintain proper battery’s state of charge (SOC) and decrease turboshaft engine’s exhaust gas temperature (EGT). First, a modeling approach based on data-driven method is adopted to obtain the mathematical model of turboshaft engine considering time delay and inertial of states. An integrated power predictor consisting of the classification of input status and the subpredictors are developed based on the deep learning method to improve the accuracy of the prediction model of the model predictive control (MPC). Subsequently, an EMS based on MPC using the proposed power predictor is introduced to regulate the SOC of battery and the EGT of turboshaft engine. The comparison with experimental results shows the high accuracy of mathematical model of turboshaft engine. The simulation results show the effectiveness of the proposed EMS for the vehicle, and the effects of different weight coefficients of objective function on the proposed EMS are discussed.
