Smart Electrical Utilization System (SEUS) is one of the most important components of smart grid (SG). It's crucial to evaluate the efficiency, safety and demand response capability of power users in SEUS. Three categories of power user evaluation (PUE) indices are presented from the aspects of energy efficiency, safety monitoring and demand response. Taking into account the uncertainty of the user...
Electricity consumption has increased substantially over the last decade. According to the Gulf Research Center (2013), residential sector represents the largest portion of electricity consumption (about 50%) in the Gulf Cooperation Council (GCC) region, due to substantial growth of electrical residential appliances. Therefore, we present a novel online smart residential load management system that...
Buildings consume a large portion of electric energy worldwide and they are also expected to actively participate in demand response under the concept of smart grid. A key premise for efficient energy utilization is energy measurement and loads control. In this paper, a Web-based Energy Management Application (WEMA) is designed and implemented based on our previous work. This application runs on a...
Recently, employing an in-network data aggregation forest has been proposed to achieve energy saving in wireless sensor networks with multiple sinks. The construction of an in-network maximum-lifetime data aggregation forest was shown NP-complete, and only one centralized algorithm in the literature was designed to solve it. The centralized algorithm suffers from significant control overhead especially...
This paper presents the concept of Dual Demand Side Management (2DSM) as an evolution of the conventional Demand Side Management concept. 2DSM accounts at the same time on one hand for the local needs, i.e. energy efficiency of the building stock as well as optimization of the local distribution grid and on the other hand for the challenges of the higher level electrical grid arising from the integration...
Increasing a functional lifetime of a network is utmost important criterion in Wireless Sensor Networks (WSNs) because of limited energy resource of nodes. Since, a functional lifetime requires either all or a certain percentage of nodes to be alive altogether, energy consumption balancing is important. Energy consumption balancing (ECB) property ensures that the average energy dissipation per sensor...
Electricity consumption in commercial and residential buildings account for around 70 percent of the total electricity consumption in the United States. Through advanced load identification and management technologies, electric energy consumption and carbon emissions in buildings can be reduced by providing fine management of energy usage in an efficient way. This paper gives a state-of-the-art review...
In 2009-2010, the California Energy Commission (CEC) funded the University of California Berkeley Building to Grid (B2G) test bed project to create a research facility that can examine aspects of electrical and other energy usage to determine total energy flows by functional use. CSUS shadowed the B2G project and documented the research test bed creation at Cory Hall on the UC Berkeley campus. The...
