The challenge of failure management emerges in decentralized architectures due to the distributed nature of the layered control process. Failures in microgrid system may occur at the microgrid level or any of the control layers. A failure detection and response mechanism is required to attain a reliable, fault-tolerant microgrid operation. This paper introduces a Failure Management Unit as an essential...
General aspects regarding software quality are discussed. Bayesian networks mathematical model is proposed to evaluate the software quality, from the reliability point of view. This model was previously used to evaluate a substation monitoring software system developed in Romania as case study. Currently, we extend it to evaluate the reliability of a software system for EMS (Energy Management Systems)...
RSE's Distributed Energy Resources Test Facility has been included as active user in A2A Lambrate Smart Grid Project. The Test Facility control system makes possible to manage the various generation systems available, behaving as a unique controllable unit by the DSO. This activity allowed to test functions such as active and reactive power control, remote disconnection and fault detection, as well...
Resent study of load management minimizes for electricity bill and peak load, but does not consider convenience about human experience. Just focused on saving energy management of the electricity price can't consider residential customers convenience. In this paper, we propose optimal load control strategy for human convenience as well as to minimize the electricity price. The strategy is to use some...

The growing share of fluctuating power generation by renewable resources and the increasing distribution of battery electric vehicles require the integration of intelligent Energy Management Systems (EMS) into the electrical power grid. Smart Homes will be equipped with controllable consumers, suppliers and storages to realize a flexible consumption and supply of thermal and electrical energy. In...
With smart grid typically characterized by attributes like, reliable and secure, efficient and economic, environment friendly and safe to the extreme extent as feasible, it calls for quality transmission and distribution operation backed by generation with optimum utilization of assets considering expected level of commitment from all stakeholders. Latter encompass investors, owners, traders, service...
From the characteristics in regional grid, the connotation of smart grid and the change of regulation and control integrated management after meeting the requirement of operating monitoring and scheduling management in regional smart grid, statements production of EMS and simulation training of dispatcher in the region smart grid were discussed in this paper.
Home/building energy-management systems (EMSs) driven by information technology are expected to be key to the achievement of an upgraded energy infrastructure, such as Smart Grid. While EMS may offer monitoring, reporting, and control of energy usage, these functions simply track intermittently the energy consumption and operational states of certain appliances and equipments. Further, since their...
The future success of the Smart Grid (SG) depends on many technological developments and innovations being created. The SG will be characterized by decentralized generation, improved network communications, demand response, greater reliability and robustness to failures. The future power grid will also have many interacting components needing greater capabilities to coordinate and manage power and...
In our approach, we model an ICT-architecture for the utility domain for both transmission and distribution grids according to the IEC standards 61968 and 61970. To achieve this, we use three basic components. The first component is the Common Information Model (CIM) which is standardized by the IEC 61970/61968 standards. The OPC UA (Unified Architecture) is the second basic component. The OPC UA...
In recent years, to build smart grid becomes a new focus, and how to fully collect and make effective use of the information of the intelligent secondary device get abroad attention. This paper presents a grid fault information intelligent analysis and processing system. It is a platform of fault information intelligent processing, used for an incorporate control center system of province and district...
There are many types of Energy Management Systems (EMS) that may be found in the industrial, commercial, and residential sectors. These systems range from the largest and most complex ones found in power generation and industrial plants down to the smallest and simple systems utilized by the residential consumer of energy. Independent of the magnitude and sophisication of the application, each type...
