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 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.


The article deals with the methods of using and improving the work of the simulation modelling method in architectural design. As a result, the authors have tried to optimize their work with criteria such as energy demand, environmental impact, geometry, and materials. The rational use algorithm of these software products in the integrated design of energy efficiency improvement of buildings, complexes and urban structures have been proposed
