Demand Side Management in Power Distribution Systems Algorithmic Development for Peak Demand Shaving

摘要

Overloading is one of the most significant challenges in the electric network. It causes abrasion and sometimes energy shortages. In the past, this problem used to be solved by suppliers of electricity. Over the last decade, researchers have been working on new technological advancements within the realm of "smart grid", where electricity customers and consumers are offered a more active role than they used to have earlier, and they are able to manage their loads and electricity consumptions. This opportunity is called demand side management (DSM). This system is suitable for residential houses or commercial buildings. With demand-side management, systems become more intelligent, and both supplier and consumer sides become active. Demand-side manager works as a time manager, where it controls all loads and decides which load to be active in different time periods.;This thesis is focused on development of a demand-side management control algorithm in a residential house, aiming at the creation of higher flexibility in demand and a better integration of the renewable technologies locally. To make a decent algorithm applicable to real world scenarios, physical models of appliances within a house are developed and several different scenarios are investigated, where customer comfort and local limits are taken into consideration.
