Seeking to solve problems in the power electric system (PES) related to exacerbated and uncontrolled energy consumption by final consumers such as residences, condominiums, public buildings and industries, electric power companies (EPC) are increasingly seeking new information and communication technologies (ICTs) to transform traditional electric power distribution networks into smart grids (SG). With this implementation, PES will be able to remotely control electric power consumption as well as monitor data generated by smart meters (SM). However, Internet-of-Things (IoT) technologies will enable all this to happen quickly and at low cost, since they are low-cost devices that can be deployed quickly and at scale in these scenarios. With this in mind, this work aimed to study, propose, and implement a hybrid communication infrastructure with LoRaWAN and LoraMesh for the demand-side management as a service (HyDSMaaS) using IoT devices such as long range (LoRa) to provide an advanced metering infrastructure (AMI) capable of performing all these applications as a service offered by EPC to end consumers. Additionally, services such as demand-side management (DSMaaS) can be used in this infrastructure. From the preliminary results it was found that the LoRaWAN network achieved a range of up to 2.35 km distance and the LoRaMESH one of 600 m; thus, the latter is more suitable for scenarios where there is little interference and the SMs are at long distances, while the other is used for scenarios with greater agglomeration of nearby SMs. Considering the hybridized scenario between LoraWAN and LoRaMESH, it can be seen that the implementation possibilities increase, since its range was approximately 3 km considering only one hop, and it can reach 1023 devices present in a mesh network. Thus, it was possible to propose the actual implementation of LoRaWAN and LoRaMESH protocols as well as the hybridization of the two protocols for HyDSMaaS. Additionally, the results obtained are exclusively from Radioenge’s LoRa technology, which can be further improved in the case of using more powerful equipment.

“…O conceito de redes inteligentes trabalha com a possibilidade de comunicação entre os dispositivos presentes no sistema elétrico. Há diversos trabalhos na literatura que propõem arquiteturas de comunicação para inversores inteligentes, sendo alguns voltados ao controle de magnitudes de tensão, como em [23], no qual uma infraestrutura de comunicação para o controle da magnitude da tensão em sistemas de transmissão de potência é proposta; em [24] é proposta uma arquitetura de controle de tensão descentralizada e não hierárquica baseada em agentes fuzzy cooperativos; e em [25] um estudo foi realizado para para avaliar a performance da comunicação no controle de inversores inteligentes com o objetivo de controlar as magnitudes de tensão em redes de distribuição.…”

A penetração da geração fotovoltaica distribuída nas redes de distribuição tornou-se uma realidade; entretanto, ainda impõe desafios a serem superados, como o funcionamento dessas redes com desvios mínimos nos perfis de magnitude de tensão. Assim, este trabalho propõe o planejamento diário da operação horária de redes de distribuição visando minimizar o desvio nos perfis de magnitude de tensão por meio de ajustes de tap ótimos de transformadores em subestações, ajustes ótimos de bancos de capacitores chaveados remotamente ao longo dos alimentadores primários e injeções de potência ativa e reativa da geração fotovoltaica distribuída por inversores inteligentes. Em tal problema, as variáveis de controle discretas associadas aos taps de transformadores e susceptâncias equivalentes de bancos de capacitores chaveados remotamente são tratadas por função penalidade senoidal que modificam o problema de programação não linear inteira mista original em um problema de programação não linear com apenas variáveis de decisão contínuas. Os resultados obtidos para redes de distribuição com 69 e 135 nós mostram que o modelo OVV proposto e sua metodologia de resolução são eficientes na redução do desvio nos perfis de magnitude de tensão e, ao mesmo tempo, na redução da demanda geral de potência reativa da rede de distribuição.

“…All adjustment procedures are supported by a communication infrastructure, which transmits the information used to determine the state of systems and passes commands to be carried out to control devices. In communication infrastructure, all data traffic is provided by WiMAX wireless technology (Worldwide Interoperability for Microwave Access), considering that this technology defines specifications of the MAC and physical layers for wireless broadband access [116].…”

The appeal for more reliable, efficient and resilient power grids has become indispensable with the recent technological development and ever-increasing demand for electrical energy. These goals might be achieved by introducing sensors and actuators in the power grid, with the purpose of enabling a smart control of the power network. All power devices must be connected using a reliable communication network, which should be able to operate even when the power grid fails. Currently, several communication technologies have been applied for supporting this new application scenario. This paper aims for reviewing both academic and market use cases for technologies applied to the mission-critical, control networks and Smart Grid applications, such as teleprotection, self-healing, communication with control centers and field devices, among others. More specifically, the key aspects, potential technologies, main protocols and use cases of operating data networks in energy transmission, power distribution and smart grid environments, including circuit and packet switching technologies, are discussed into details. Furthermore, resilience and the main telecommunications technologies used in power grids, as well, the correlation among them, are exploited in practical point of view. The article provides a broad discussion on the best telecommunication options to build the emerging intelligent energy distribution systems, covering control networks, teleprotection, and smart grid applications.
