Information System Functions for smartgrid Management

Sociology Study 2016年第2期6卷 96-103页

作者： Mila llieva-Obretenova University of Mining and Geology Sofia Bulgaria

The violently penetration of renewables in power supply network leads to situations, by which the offer exceeds the demand. Therefore, it is necessary to include a system for processes＇ management. smartgrid is a platform over the power supply network. It is represented with its network and services, which also have to be managed. The paper aims to show the second stage of smartgrid management modeling. It meets heterogeneous requirements of the actors--subscriber without photovoltaics, subscriber with photovoltaics, service provider, network operator, and network elements operator--to service and network management and is oriented to functional areas, covering the life cycle of power supply service： Design, Planning, Installation, Provision, Configuration, Maintenance, Performance, Accounting, Buying Up, Security and Subscriber Control. Functional models for existing networks--telecommunications--are used and they are adapted to power supply. The results are illustrated with three functional areas for service management： Accounting, Buying Up, and Performance. The synthesis of network management functions and network element management functions are similar.

Demand Side Management for Thermally Activated Building Systems Based on Multiple Linear Regression

引用

Journal of Electronic Science and Technology 2015年第4期13卷 355-360页

作者： Martin Schmelas Julien H?ll Elmar Bollin the Institute of Energy System Techniques Offenburg University of Applied Sciences the Department of Microsystems Engineering University of Freiburg

The building sector and its heating and cooling represents one of the major consumer of energy worldwide. Simultaneously, the share of fluctuating generation of renewable energies in the energy mix increases. Therefore storage and demand side management technologies are required. The new adaptive and predictive control algorithm for thermally activated building systems （TABS） based on multiple linear regression （AMLR） presented in this paper enables the application of demand side management （DSM） strategies. Based on simulations, different strategies have been compared with each other. By applying the AMLR algorithm, electricity energy cost savings of 38% could be achieved compared to the conventional control strategy for TABS, while increasing the thermal comfort. At the same time, thermal energy demand can be reduced in the range between 4% to 8%, and pump operation time from 86% to 89%.

关键词： Demand side management smartgrid thermal storage thermally activated buildingsystems.
