Overloading is one of the most significant challenges in the electric network. It causesabrasion and sometimes energy shortages. In the past, this problem used to be solved bysuppliers of electricity. Over the last decade, researchers have been working on newtechnological advancements within the realm of “smart grid”, where electricity customers andconsumers are offered a more active role than they used to have earlier, and they are able tomanage their loads and electricity consumptions. This opportunity is called demand sidemanagement (DSM). This system is suitable for residential houses or commercial buildings.With demand-side management, systems become more intelligent, and both supplier andconsumer sides become active. Demand-side manager works as a time manager, where itcontrols all loads and decides which load to be active in different time periods.This thesis is focused on development of a demand-side management controlalgorithm in a residential house, aiming at the creation of higher flexibility in demand and abetter integration of the renewable technologies locally. To make a decent algorithmapplicable to real world scenarios, physical models of appliances within a house aredeveloped and several different scenarios are investigated, where customer comfort and locallimits are taken into consideration.
