Problems Evoked by The Integration of Renewables as Parts of Building Energy Management Systems

Nowadays, the search for optimal realization of how to get disconnected from the power grid has become a trend. There has been a great variety of solutions revealed which operate as completely [1], [2] or partly [3] “off-grid” systems. In the future, the assurance of proper energy management, power quality and dependability will be a key question in the operation of these networks. When considering different environment-friendly energy sources for this purpose, we cannot leave out the implementation of an energy storing utility in order to straighten out the differences in the daily energy production and demand [4]. The decrease in prices of energy storing technologies happened over the course of the last decades also matches the evolvement of introducing the upper-mentioned utility. In my paper I will use up- to-date energy data basing my calculations to reveal an energy storing solution capable to balance the energy use of an average household which also serves as energy producer [5]. Apart from the minimization of the downside effects of feeding back into the grid, it is also aimed to provide service continuity and the elimination of voltage fluctuation as the results of electing the adequate energy storage utility and elaborating a supporting building management system [6].
