Justino Miguel Rodrigues nasceu em Penafiel (Portugal) a 9 de Setembro de 1985. Obteve o grau de Mestre em Engenharia Eletrotécnica e de Computadores pela Faculdade de Engenharia da Universidade do Porto em Julho de 2010.

Em Dezembro de 2010 integrou o INESC TEC como membro da equipa de investigação do projeto REIVE – Redes Elétricas Inteligentes com Veículos Elétricos - com vista ao desenvolvimento de modelos de simulação computacionais de protótipos de conversores eletrónicos incorporando funcionalidades de controlo avançadas desenvolvidas no âmbito desse projeto.

Integrou em 2013 o projeto COMUTE-DC, onde participou no desenvolvimento da infraestrutura laboratorial para implementação de uma rede DC multi-terminal em escala reduzida, e foi responsável pela realização dos ensaios laboratoriais de validação das funcionalidades avançadas direcionadas para redes DC multi-terminal desenvolvidas no âmbito do projeto.

Integra atualmente o projeto SENSIBLE desde 2016, onde ficou encarregue do desenvolvimento de modelos de simulação computacionais para a validação da integração de sistemas de armazenamento de energia em redes de baixa tensão, tendo em vista a capacidade de sobrevivência a cavas de tensão e operação em ilha. Está igualmente envolvido no desenvolvimento de algoritmos de otimização para a gestão ótima de unidades de armazenamento de energia integradas nas redes de média tensão e baixa tensão que integrarão o demonstrador final. 

Transversal a todas atividades anteriores, é também responsável pelo desenvolvimento do software Lab Device Manager, projetado para facilitar e tornar mais acessível a implementação, gestão e monitorização de experiências laboratoriais utilizando todos os equipamentos e infraestrutura disponível no Laboratório REIVE.

Do trabalho desenvolvido foi possível desenvolver conhecimentos na área da programação e automação, que constituem um complemento valioso à formação base em sistemas elétricos de energia e em energias renováveis.

Abstract
The progressive decommissioning of large synchronous generators that should take place in face of increasing penetration ratios of Distributed Generation (DG) will demand additional control mechanisms for inertia provision and frequency and voltage regulation in the power system. The need to cope with increasing penetration ratios of DG in distribution grids, added to the necessity to integrate an expected massification of EV and distributed ESS, and to the necessity to enhance Power System resilience and controllability, makes the Smart-Transformer (ST) a suitable solution. In this paper it is demonstrated the feasibility of the ST to contribute to frequency control through the control of the resources available in the distribution AC/DC hybrid networks created from the ST. The feasibility of local droop controllers, acting on frequency and voltage magnitude of the AC/DC hybrid networks created from the ST, to achieve the aforementioned goal, is demonstrated through computational simulation. © 2019 IEEE.

Abstract
Renewable energy sources are environmentally appealing in electrical power grids. However, distributed energy resources (DER) are typically connected to the grid through converters that do not have the same properties as synchronous generators which have high participation in power generation. Some of these properties like inertial response are important and must not be lost with higher DER penetration. The present paper analyses two converter control algorithms that are capable of emulating inertial response in DER: the Virtual Synchronous Generator control (VSG) and the Synchronverter. Both algorithms are described, implemented and tested in a practical experiment and a comparison of both algorithms is assessed in terms of frequency nadir achieved, settling time and implementation complexity. The findings can give useful insights to help decide which algorithm should be implemented in a future real application. © 2018 Power Systems Computation Conference.

Abstract
The large scale integration of Distributed Energy Resources (DER) at the Low Voltage (LV) distribution network offers new opportunities for the improvement of power quality and network reliability. Currently, the occurrence of large disturbances at the transmission network causing severe voltage sags at the distribution level could lead to the disconnection of a large share of DER units connected to the LV network, causing a more severe disturbance. In this paper, Low-Voltage-Ride-Through (LVRT) requirements and current support strategies are proposed to mitigate the impact of severe voltage sag at the distribution level for DER units connected to LV network. The impact of adopting the proposed LVRT strategies will be analyzed through simulation and experimentally. A developed in house ESS prototype incorporating the developed LVRT strategies is also presented, and its capacity to comply with the proposed LVRT requirements is demonstrated using an experimental Power-Hardware-in-the-Loop (PHIL) setup. © 2018 Power Systems Computation Conference.

Testing of smart converters for grid-code compliance with power-hardware-in-the-loop

2018 INTERNATIONAL CONFERENCE ON SMART ENERGY SYSTEMS AND TECHNOLOGIES (SEST)

Abstract
Using power-hardware-in-the-loop is a solution for testing the behavior of devices on an emulated grid, with greater flexibility and avoiding the introduction of disturbances or critical operating conditions in the utility grid. This paper highlights the implementation of such a setup, its challenges and the solutions to cope with its limitations. The emulated grid is then used for the experimental validation of a 10kVA converter, regarding fault-ride-through, dynamic reactive current support and frequency and voltage based droop control, leading to the identification of design improvement recommendations.

Abstract
A distinctive characteristic of a Microgrid (MG) system is related to the ability of operating autonomously. However, the stability of the system relies in storage and generation availability, providing frequency and voltage regulation. Considering the deployment of distributed storage units in the Low Voltage network and of smart metering infrastructures, this paper presents an online tool for promoting an effective coordination of MG flexible resources in order ensure a secure autonomous operation and maximize the time that the MG is able to operate islanded from the main grid. The tool determines a priori an emergency operation plan for the next hours, based on load and microgeneration forecasting. The limited energy capacity of the distributed storage units participating in MG control is also considered.
