- Real-Time Emulation and Simulation System of Asynchronous Motor ConsumptionPublication . Sousa, Filipe; Spínola, João; Moreira, Nuno; Faria, Pedro; Vale, ZitaElectric power systems have been altered at the operating and planning level in the last years. Evidence of this was the liberalization of the energy market and the implementation of concepts such as smart grids and the active participation of consumers through demand response programs. The main objective of the present paper is to propose an emulation model for asynchronous motors, in the scope of dynamic measurement and control of loads, included in demand response programs. Since this type of electric motor is of upmost importance in the current consumption context, it was necessary to model consumption and evaluate its impact on the power system. The development of this paper aims to evaluate the system’s capabilities using the motor as a load, and a wind emulator. Thus, we can represent various applications (e.g. division of a house) and realize the effect of distributed generation in the operation of the electric power system.
- A Residential House Comparative Case Study Using Market Available Smart Plugs and EnAPlugs with Shared KnowledgePublication . Gomes, Luis; Sousa, Filipe; Pinto, Tiago; Vale, ZitaSmart home devices currently available on the market can be used for remote monitoring and control. Energy management systems can take advantage of this and deploy solutions that can be implemented in our homes. One of the big enablers is smart plugs that allow the control of electrical resources while providing a retrofitting solution, hence avoiding the need for replacing the electrical devices. However, current so-called smart plugs lack the ability to understand the environment they are in, or the electrical appliance/resource they are controlling. This paper applies environment awareness smart plugs (EnAPlugs) able to provide enough data for energy management systems or act on its own, via a multi-agent approach. A case study is presented, which shows the application of the proposed approach in a house where 17 EnAPlugs are deployed. Results show the ability to shared knowledge and perform individual resource optimizations. This paper evidences that by integrating artificial intelligence on devices, energy advantages can be observed and used in favor of users, providing comfort and savings.
- An Intelligent Smart Plug with Shared Knowledge CapabilitiesPublication . Gomes, Luis; Sousa, Filipe; Vale, ZitaThe massive dissemination of smart devices in current markets provides innovative technologies that can be used in energy management systems. Particularly, smart plugs enable efficient remote monitoring and control capabilities of electrical resources at a low cost. However, smart plugs, besides their enabling capabilities, are not able to acquire and communicate information regarding the resource's context. This paper proposes the EnAPlug, a new environmental awareness smart plug with knowledge capabilities concerning the context of where and how users utilize a controllable resource. This paper will focus on the abilities to learn and to share knowledge between different EnAPlugs. The EnAPlug is tested in two different case studies where user habits and consumption profiles are learned. A case study for distributed resource optimization is also shown, where a central heater is optimized according to the shared knowledge of five EnAPlugs.

- An Agent-Based IoT System for Intelligent Energy Monitoring in BuildingsPublication . Gomes, Luis; Sousa, Filipe; Vale, ZitaThe new power system paradigm demands a more active end-consumer participation in smart grids environment. To achieve this participation, new demand side management solutions should be developed and analyzed. Moreover, the massive dis- semination of internet of things devices inside buildings are a reality in nowadays. This paper proposes a multi-agent system for microgrid representation that integrates internet of thing devices to boost the energy management in today's buildings. The paper will present the proposed multi-agent system as well as an environmental awareness smart plug. The case study in this paper will present the data acquisition from a real building using a combination of market internet of things smart plugs, the proposed environmental awareness smart plug and a load emulator.
- Indoor Real-Time Locating System comparison: Polaris vs FIND3Publication . Silva, David; Gomes, Luis; Sousa, Filipe; Vale, ZitaThe use of real-time locating systems can be used in several fields, from security and health to building and energy management. However, there is no consensus in what the better solution or technology is to be used in an indoor location system. This paper presents a comparative study between a market real-time locating system and an open source real-time locating system. The systems that will be compared are Polaris and FIND3. The tests were performed in an office building.
- Microgrid Demonstration Platform: Modbus TCP/IP Connection for Real-Time Monitoring of a Wind TurbinePublication . Sousa, Filipe; Spínola, João; Zawiślak, KrzysztofSeveral countries promote wind energy despite their high installation cost, since over time these investments can become profitable. It is important that energy entrepreneurs have up-to-date information of operation parameters, to identify places where excessive energy consumption occurs. For energy management, it is necessary to have an overview of the whole system, such that reporting and further result analysis can be made. With monitoring and control systems, it is possible to enable an improved management of resources, especially in terms of balance between generation and consumption. In this work, it is proposed a graphical interface to monitor and control a wind turbine, in a simulation environment running four operation scenarios.
- Radio-Frequency communication in a SCADA system for the monitoring and control of intelligent building and office blocksPublication . Sousa, Filipe; Faria, Pedro; Coppens, Tom; Vale, ZitaThe efficient use of electricity and how people approach it, is a topic that has a big impact on the environment and society. The consumption management will be improved by the monitoring and the controlling of electrical installations. Communication is a key part in this process and that is why the improvement of data transmission is very important to obtain a controlled process. Transferring data is achieved by sending an electromagnetic signal by means of different types of communications channels. This paper presents a connection between a superior network and an external one to create the possibility of monitoring and controlling devices linked to the networks in a research institution (GECAD). The communication devices used are modems which use radio waves to make the transmission. A program has been created to access the data of an energy meter to obtain knowledge on how to implement analyzers in a SCADA system to improve monitoring of an electrical installation. This assignment will achieve a better understanding of the different protocols and operation modes.
- EnAPlug – An Environmental Awareness Plug to Test Energy Management Solutions for HouseholdsPublication . Gomes, Luis; Sousa, Filipe; Vale, ZitaThe present paper presents a new kind of Smart Plug that covers the needs of power systems R&D centers. EnAPlug, described in this paper, enables the monitor and control of loads, as a normal Smart Plug. However, it has a great benefit in comparison with a normal Smart Plug, the EnAPlug allows the integration of a variety of sensors so the user can understand the load and the surrounding environment (using a set of sensors that better fit the load). The sensors are installed in the load itself, and must have a clear fit to the load. The paper presents a demonstration of an EnAPlug used in a refrigerator for a demand response event participation, using the sensor capability to measure important values, such as, inside temperature.
