The stability conditions of the power supply system with solar panel and diesel generator are studied. It is shown that the ratio between solar panel and load currents affects the stability of systems with distributed generation. The extension of stability workspaces is achieved by using the storage battery as a device that increases the system stability.

The paper deals with the voltage source multilevel inverter space vector PWM algorithm developed on the base of one of the more general algorithms for oblique-angled coordinates of two delta voltages. The symmetry of the instantaneous output voltages on the clock cycle is provided by the simple control for the performing of the preset five-segment switching sequence. The calculations being used are quite simple and fast so they can be performed even applying a cheap DSP.

Effective load control task in Smart House is considered using mathematics of structural numbers. Separate structural number in the form of one-column matrix is to be formed for each load according to its characteristics. Merging of separate load matrices leads to common structural number describing the state of all loads. Thus, the possibility of energy-efficient load control appears with clear and simple algorithm of realization.

An algorithm of fault location's detection and resistance's value assessment is described for overhead lines with distributed load in case of isolated neutral. The method is based on the results of measurement of line's mode parameters. A mathematical model is proposed considering the influence of the voltage of the line two wires - rail mode operation-line power automation. Capacitances are placed between each phase line and the ground to increase the accuracy of the method. Accuracy of determining the values of resistance in fault location is analyzed.

This article presents the analysis of electromagnetic processes in MOSFET switch of a zero-current switching quasi-resonant pulse converter with series resonant circuit. The analysis performed by stitching equations illustrating change of MOSFET current and MOSFET voltage. The obtained results for each switching interval allowed to estimate the overall power dissipation and power losses for all switching intervals.

A possibility of application of power harmonic analysis method to an electrohydraulic complex with nonlinear processes in the pipeline system is demonstrated. It is determined that nonlinear processes in a hydraulic network, caused by cavitation self-oscillations, result in periodical stationary oscillations of power, are accompanied by increase of its variable component. To assess the processes of energy conversion in the electrohydraulic complex it is proposed to use indices based on determination of root-mean-square values of power.

In the southern part of Ukraine, the increasing of the installed capacity of the solar power plants (SPP) effects on load-frequency control in the interconnected power system (IPS) of Ukraine. In order to mitigate power flow fluctuations due to the stochastic generation of SPP, the local active power controller (LAPC) is proposed. LAPC generates a control signal to the units of the regulating power plant. The structure diagram of such controller is presented and simulation results of LAPC operation considering SPP generation are shown. The developed model is used to study the impact of SPP on load-frequency control in power systems.
