Demand modeling for assessing the impacts of micro-generation in a low voltage radial distribution network

An accurate and detailed assessment of the impacts of micro generation units in radial low voltage distribution networks asks for adequate modeling of both demand and micro generation uncertainty. In this paper we describe the methodological steps followed to characterize the demand patterns and micro generation availability taking into consideration the typical uncertainties associated with both the demand and generation. Monte Carlo simulations have been used to reproduce realistic load and generation curves, allowing a detailed evaluation of the impacts of micro-generation units on voltage profile and losses. The results of applying such methodology in a real low voltage distribution network are presented.
