The evolutionary integral dynamical models of storage systems are addressed. Such models are based on systems of weakly regular nonlinear Volterra integral equations with piecewise smooth kernels. These equations can have non-unique solutions that depend on free parameters. The objective of this paper was two-fold. First, the iterative numerical method based on the modified Newton–Kantorovich iterative process is proposed for a solution of the nonlinear systems of such weakly regular Volterra equations. Second, the proposed numerical method was tested both on synthetic examples and real world problems related to the dynamic analysis of microgrids with energy storage systems.

Abstract With the transformation of power utility companies from vertical structure to full deregulated entities, the need for the integration of distributed generation (DG) resource in the form of Microgrid (MG) system would soon become indispensable in most deregulated power systems. This is due to renewability of such generation systems. The power quality performance in terms of intermittent energy of these DG systems supply is the major limitation to their full integration as the sole generation entities that can propel rapid decentralization of electric power systems operation. Nonetheless, the acceptable standard is to operate them in an islanding mode or as a MG optimally dispatch among generation mix. This paper developed a total harmonic distortion models for a Microgrid bus in a Nigerian grid system and applied Monte Carlo technique to reliably predict the level of harmonic power flow in the system. The result shows that the distortion increases as the demand factor of the station decreases.
