The energy resource management is becoming increasingly important and complex, because of the growing use of distributed generators and electric vehicles connected to the distribution network. This paper presents a platform to be used by virtual power players regarding the energy resource management in smart grids and considering day-ahead, hour-ahead, and real-time time-horizons. This method considers that the energy resources are managed by a virtual power player that establishes contracts with their owners. Two approaches are presented to the real-time scheduling, the use of direct load control demand response events, and the use of real-time pricing demand response. The model uses full AC power flow to take into account network constraints. A case study with a 33-bus distribution network and a large number of distributed energy resources is used to illustrate the platform.

The use of demand response programs brings several advantages to the power systems operators, to the consumers, as well as to the proper functioning of the whole electrical power system. The present paper proposes a methodology based on the use of five types of demand response programs (Steps, Quadratic, Constant, Linear and Elasticity). These programs corresponds to distinct approaches to model the consumer participation in demand response programs. This methodology can be used by a Virtual Power Player that aggregates and manages the small size consumers demand response for the participation in demand response programs. Distinct consumption reduction levels have been implemented in a case study composed by 218 consumers. The aggregator becomes able to discuss on the remuneration approach adequate for each reduction level and consumer type.

The market globalization and the firms’ internationalization hinder the matching of the top managers’ agenda, making it difficult to meet in the same space or time. On the one hand, the appearance of Ubiquitous Group decision support Systems (UbiGDSS) ena-bled individuals to gather and make decisions in different spaces at different times, but on the other hand, originated problems related to the lack of human interaction. To under-stand how the arguments used can influence each of the decision-makers, what is their satisfaction regarding the decision made, and other affective issues such as emotions and mood, are some examples of that lack. In order to try to overcome this lack, we propose a theoretical model that is specially designed for agents, helping to understand the interac-tions impact on each agent and their satisfaction with the decision made. © 2015 SERSC.

The increasing and intensive integration of distributed energy resources into distribution systems requires adequate methodologies to ensure a secure operation according to the smart grid paradigm. In this context, SCADA (Supervisory Control and Data Acquisition) systems are an essential infrastructure. This paper presents a conceptual design of a communication and resources management scheme based on an intelligent SCADA with a decentralized, flexible, and intelligent approach, adaptive to the context (context awareness). The methodology is used to support the energy resource management considering all the involved costs, power flows, and electricity prices leading to the network reconfiguration. The methodology also addresses the definition of the information access permissions of each player to each resource. The paper includes a 33-bus network used in a case study that considers an intensive use of distributed energy resources in five distinct implemented operation contexts. © IFAC.

The development in power systems and the introduction of decentralized generation and Electric Vehicles (EVs), both connected to distribution networks, represents a major challenge in the planning and operation issues. This new paradigm requires a new energy resources management approach which considers not only the generation, but also the management of loads through demand response programs, energy storage units, EVs and other players in a liberalized electricity markets environment. This paper proposes a methodology to be used by Virtual Power Players (VPPs), concerning the energy resource scheduling in smart grids, considering day-ahead, hour-ahead and real-time scheduling. The case study considers a 33-bus distribution network with high penetration of distributed energy resources. The wind generation profile is based on a real Portuguese wind farm. Four scenarios are presented taking into account 0, 1, 2 and 5 periods (hours or minutes) ahead of the scheduling period in the hour-ahead and realtime scheduling. © IFAC.

Electric vehicles (EV) can become integral part of a smart grid because instead of just consuming power they are capable of providing valuable services to power systems. To integrate EVs smoothly into the power systems, a multi-agents system (MAS) with hierarchical organization structure is proposed in this paper. The proposed MAS system consists of three types of agents: distribution system operator agent (DSO agent), electric vehicle fleet operator agent (EV FO agent or alternatively called virtual power plant agent) and EV agent. A DSO agent belongs to the top level of the hierarchy and its role is to manage the distribution network safely by avoiding grid congestions and using congestion prices to coordinate the energy schedule of VPPs. VPP agents belong to the middle level and their roles are to manage the charge periods of the EVs. EV agents sit in the bottom level and they represent EV owners and operate the charging behaviour of EVs. To simulate this collaborative (all agents contribute to achieving an optimized global performance) but also competitive environment (each agent will try to increase its utilities or reduce its costs), a multi-agent platform was developed to demonstrate the coordination between the interacting agents. © Springer-Verlag Berlin Heidelberg 2014.

Nowadays the incredible grow of mobile devices market led to the need for location-aware applications. However, sometimes person location is difficult to obtain, since most of these devices only have a GPS (Global Positioning System) chip to retrieve location. In order to suppress this limitation and to provide location everywhere (even where a structured environment doesn’t exist) a wearable inertial navigation system is proposed, which is a convenient way to track people in situations where other localization systems fail. The system combines pedestrian dead reckoning with GPS, using widely available, low-cost and low-power hardware components. The system innovation is the information fusion and the use of probabilistic methods to learn persons gait behavior to correct, in real-time, the drift errors given by the sensors. © Springer International Publishing Switzerland 2014.

Most of distributed generation and smart grid research works are dedicated to network operation parameters studies, reliability, etc. However, many of these works normally uses traditional test systems, for instance, IEEE test systems. This paper proposes voltage magnitude and reliability studies in presence of fault conditions, considering realistic conditions found in countries like Brazil. The methodology considers a hybrid method of fuzzy set and Monte Carlo simulation based on the fuzzy-probabilistic models and a remedial action algorithm which is based on optimal power flow. To illustrate the application of the proposed method, the paper includes a case study that considers a real 12-bus sub-transmission network.

This paper addresses the problem of MicroGrid (MG) management including Electric Vehicles (EV) scheduling in a low voltage residential grid. The methodology uses a deterministic algorithm approach implemented in TOMLAB software. A realistic case study using a 25-bus MG with distributed generation, dispersed storage and EVs is provided to demonstrate the use of this application. The method runs in less than 1 second while minimizing operation costs and improving the benefits of the MG. The potential benefits of storage units are demonstrated when high PV power production is available.
