Modeling of the modes of operation of wind energy installations in hybrid power supply systems

The article presents modern schemes for the organization of wind-solar power supply systems. Available approaches to managing the energy-dynamic process of operation of wind power plants as part of hybrid power supply systems are given, and modern research on this topic is given. The results of the development of a mathematical model of the energy-dynamic processes of the hybrid wind-solar power supply system, which includes wind power plants, solar panels, and a battery energy storage system. The universal structural diagram of such a system is substantiated.

Minimization of public transport delays at arterial streets with coordinated motion

Research results, using which the method of minimization of public transport delay is improved at intersections with the system of coordinated motion control, are given in this paper. Such transport research was carried out with simultaneous application of field measurements of the study of traffic flow indicators and computer simulation in PTV VISSIM to check the level of efficiency of coordinated control and the reliability of the results.

Minimization of traffic delay in traffic flows with coordinated control

The method and results of transport research, carried out by field research method, on the determination of the main indicators of traffic flows with significant unevenness of the movement on the arterial street in conditions of coordinated control is reviewed in the paper. Time parameters of traffic light control for which a reduction in traffic delay is achieved in direct and opposite traffic flow by the change of permissive signal depending on traffic intensity are determined using the simulation method.

Дослідження інтегральної нелінійності сигма-дельта модулятора другого порядку

Досліджено вплив інтегральної нелінійності функції перетворення інтеграторів сигма-дельта модулятора другого порядку на інтегральну нелінійність функції перетворення модулятора загалом. За результатами досліджень визначено вигляд функції нелінійності модулятора та коефіцієнти впливу кожного інтегратора.
