Kоnvеnciоnаlnе mеtоdе uprаvlјаnjа pоtrоšnjоm mеnjајu svојu suštinu u mrеžаmа sа znаčајnim udеlоm vаriјаbilnе prоizvоdnjе јеr, pоrеd smаnjеnjа vršnоg оptеrеćеnjа, mоgu da оdigrаju i ulоgu sklаdištеnjа еnеrgiје, dоprinоsеći tаkо bаlаnsirаnju snаgе u sistеmu.

The subject of this dissertation and its basis represents the investigation of potential and possible effects of demand side management (DSM) and demant response (DR) in the Smart power distribution grid concept with variable generation. Conventional load control methods change their essence in the grids with significant impact of variable generation. Namely, beside peak load reduction, these methods can play the role of energy storage, improving the energy balance in the system. Therefore, it was reasonable to anaylize technical possibilities of remote control of a part of the consumption. Researches, calculations and analyses have been conducted using examples of chosen parts, as well as the whole, integral consumption area of Electricity Distribution Company Belgrade, „Еlеktrоdistribuciјa Bеоgrаd“ (ЕDB). The tasks and goals of this dissertation were the following: - to examine and perceive total capacity in heat consumers (heat storage furnaces, storage water heater, etc.) within EDB's consumption area, as well as the capacity of other devices suitable for energy storage; - to develop estimation method(s) of some area's DSM/DR potential (capacity) for balancing consumption load with strongly fluctuating (i.e., intermittent, variable) generation from renewable energy sources (V-RES), connected to distribution grid; - to assess the applicability of DSM/DR programs and their effectivity for peak load reduction, load shedding (daily load profile ”freezing”) and energy storage, by which the power balancing with assumed a greater expansion of V-RES could be achieved; - to develop the concept of load control as the instrument for energy storage in the „Smart + V-RES“ environment and to propose correspondent technical solution; - to propose specific manner of load control and to illustrate its apply possibilities at one chosen part of EDB's consumption area; - to present the simulation results of possible connection and operation of one kind of RES, in greater extent, combined with the application of the chosen DSM/DR model, at the same, selected part of EDB's consumption area; - to develop the methodology for long-term forecasting of the peak load, in terms of its significant and durable reduction, achieved by the application of „Smart + V-RES + DSM/DR“ concept...
