“…The costs and size of the components may become a significant factor and in certain applications where the size and weight of the added components may not be practical [14]. Multi-supply or hybrid micro-grid configurations may improve immunity to conducted EMI by implementing an inverter and/or generator in combination with a battery [15]. In this paper an isolated grid has been set up with a commercial off the shelf inverter and loads illustrated in Fig.…”

Transient currents can severely impact the operation of weak or islanded grids. Inrush current electromagnetic compatibility challenges, due to their unpredictable and intermittent nature, are very difficult to identify. Using multi-point synchronised measurements, analysis is performed on an inverter. The supply powers various loads that are observed during cold start as well as under load switching conditions. Inrush event triggered failure probability is linked to non linear and average load levels.

“…In other researches, the extension of stability workspaces is achieved by using a battery energy storage system (BESS) as a device that increases the system stability [30] [31]. In [30], for example, a BESS is suggested to generate the nominal system frequency, instead of a synchronous generator. From a frequency control perspective, this makes the system frequency independent of the mechanical inertia of the synchronous generator [30].…”

“…To build a wide range of power supply systems, such as: frequency converters for controlled AC drive, power supply systems from renewable energy sources -windmills and solar panels, widely used three-phase stand-alone inverter [1], [6], [7], [10]. In some cases, such an application requires the formation of not only the output sinusoidal voltage of constant amplitude and frequency, but also a constant input current of a given value.…”

To build various power supply systems, it is necessary to design a control system that would ensure electromagnetic compatibility with both the load and the source. It is proposed to apply the geometric approach to describe semiconductor power converters, which allows using input independent variables to control the output parameters. The analysis of a three-phase three-leg inverter with a symmetrical active load using a geometric approach is considered. A system of vectors is constructed on which the vectors of input values in three-dimensional space and their projections are shown, which form output values in two-dimensional and one-dimensional space. A table has been created that describes the values of currents and voltages in the converter for the corresponding switch states. Three basic vectors were selected, with the help of which all other vectors of input quantities can be obtained. Transition matrices for the input current and output voltages are obtained. An autonomous inverter control system is built using a geometric approach. The basis is a space-vector pulse-width modulation, with some changes. As a result, the problem of losing the degree of freedom by abandoning the polar coordinate system when switching to another reference system was solved. The solution was the introduction of a spherical coordinate system, which allows you to rotate the control vector in three-dimensional space. As a result, time diagrams of output voltages and currents corresponding to the theoretical ones are obtained. Most units in the control system under the mask implement the program code MATLAB: the transition from a three-dimensional Cartesian coordinate system to a rotating spherical, sector selection, the length of the reference vector and the value of angle, the duration of pulse-width modulation for each sector. The shape of the output voltages has a stepped shape. The shape of the generated currents repeats the shape of the output voltages.
