A hybrid energy storage system (HESS) composed of a battery and super-capacitor (SC) can make full use of advantages in energy and power density, which can further improve the performance of hybrid electric vehicles (HEV). Most studies have been limited to configuration and control to reduce the burden and prolong the life cycle of the battery, seldom focusing on the redesign of energy manageme...

In this paper, an agent-based structure of the electricity retail market is presented based on which day-ahead (DA) energy procurement for customers is modeled. Here, we focus on operation of only one Retail Energy Provider (REP) agent who purchases energy from DA pool-based wholesale market and offers DA real time tariffs to a group of its customers. As a model of customer response to the offe...

Recently, the number of Battery Energy Systems (BESs) connected to grid has grown significantly. These assets can alleviate some operational issues such as demand surges and occasional power fluctuations associated with Renewable Sources (RESs) grid. Nonetheless, both overcharging frequent usage severely affect their health status shorten life expectancy. In this paper, an Management System (EM...

The integration of intermittent resources of power generation, such as wind and solar, will lead to unprecedented energy price fluctuations and increasing price uncertainty. Besides improving forecasting, electricity retailers can meet this challenge by partly adopting the demand side of the electricity markets to the fluctuating supply side. The necessary communication infrastructure for this ...

This paper presents the development of the distributed processing based Security Constrained Optimal Power Flow (SCOPF) and its integration to a Distributed Shared Memory Energy Management System (EMS) in order to enable real time power systems security control. The optimization problem is solved by the Interior Points Method and the security constraints are considered by the use of Benders Dec...

Smart technologies and electric vehicles are supposed to efficiently use renewable resources by shifting loads and storing surplus electricity. Although several field tests with smart meters, dynamic pricing or electric vehicles are conducted, hardly any consumer has experienced a combination of these components. So far, neither consumer perceptions nor the effectiveness of these demand respons...

C ONSUMERS are expected to play an increasingly important role in current electricity markets through smart grid systems , where risk and uncertainty are becoming central issues. The availability of an advanced metering infrastructure provides one of the building blocks for bi-directional communications between consumers and suppliers, creating an opportunity for large-scale load control within...

© 2013 Zhuang Zhao et al. 677 In this paper, we first introduce a general architecture of an energy management system in a home area network based on a smart grid. Then, we propose an efficient scheduling method for home power usage. The home gateway (HG) receives the demand response (DR) information indicating the real-time electricity price, which is transferred to an energy management contro...
