IoT Based Microgrid Automation for Optimizing Energy Usage and Controllability

01 Mar 2018-
TL;DR: IoT is used to solve the issues of microgrid reconfiguration occurring due to faults, changing energy usage patterns and inclusion and removal of DERs by using suitable processor based technology.
Abstract: Microgrids comprise low voltage distribution systems with distributed energy resources (DER) and controllable loads which can operate connected to the medium voltage grid or islanded in a controlled and coordinated way [1]. Microgrids are controlled units which report their current state to a central control unit called Central Protection Centre (CPC) thus increasing reliability of the system. This feature also increases the controllability, security and ease of power flow. By connecting load centers to a microgrid, uninterrupted power is supplied to households and industries with reduction in energy theft, interruptions and loss in energy. However the challenge lies in automating the entire process of monitoring, protection and control of all the grid parameters. This becomes more critical with inclusion of DERs as they are inconsistent sources of energy. In this paper the concepts of Internet of Things(IoT) is used to solve the issues of microgrid reconfiguration occurring due to faults, changing energy usage patterns and inclusion and removal of DERs. By using suitable processor based technology it is aimed to automate the process, reduce the cost and size of establishment and reduce the overall cost of energy to the supplier.

TL;DR: In this article, a monitoring and control system for DC microgrids that uses external computer equipment and can be accessed remotely is proposed, based on Internet of Things (IoT) and Controller Area Network (CAN) technologies.
Abstract: Communication standards commonly used in microgrids monitoring and control systems often have coverage limitations. Typically this require both the human operator and the computer equipment to be physically on site. This research aims to develop a monitoring and control system for DC microgrids that uses external computer equipment and can be accessed remotely. The proposed system is based on Internet of Things (IoT) and Controller Area Network (CAN) technologies. It uses computational resources hosted in the cloud to perform monitoring and control tasks and provides human operators with a web interface to access the system through an Internet connection. The proposed system is validated through a case study of a DC microgrid. The obtained results show that it is possible to extend the coverage and capabilities of monitoring and control systems for DC microgrids with IoT services.

TL;DR: In this article , the authors present an introductory analysis of both the scientific developments in IoT applications and the potential ecological consequences associated with increasing IoT applications, including smart cities enabled by IoT, ambient assisted living, and IoT technologies for transportation and low carbon products.
Abstract: As IoT (Internet of Things) and smart technologies have developed rapidly, many technological advancements have been made possible. The IoT’s main objective is to assist in simplifying processes in a number of different fields, to improve the efficiency of technologies and protocols, and ultimately to improve quality of life. Although IoT technologies can benefit the population in numerous ways, their development must be evaluated from an environmental viewpoint to ensure that global resources are used efficiently and to prevent negative effects. As previously described, considerable research effort is needed to explore the advantages and disadvantages of IoT technologies. Engineering professionals, industrial experts, and academic researchers successfully interacted at the conference. Several key tracks made up the conference, including smart city, energy and environment, e-health, and engineering modeling. Specifically, the editorial covered a number of topics including (i) IoT in sustainable energy and environmental management, (ii) smart cities enabled by IoT, (iii) ambient assisted living, and (iv) IoT technologies for transportation and low-carbon products. An important outcome of our introductory analysis has been a greater understanding of both the scientific developments in IoT applications and the potential ecological consequences associated with increasing IoT applications.

TL;DR: In this paper, the effect of high DG penetration on protective device coordination is explored and an adaptive protection scheme is proposed as a solution to the problems identified, which is implemented on a simulated actual distribution feeder.
Abstract: Conventional power distribution system is radial in nature, characterized by a single source feeding a network of downstream feeders. Protection scheme for distribution system, primarily consisting of fuses and reclosers and, in some cases, relays, has traditionally been designed assuming the system to be radial. After connecting distributed generation (DG), part of the system may no longer be radial, which means the coordination might not hold. The effect of DG on coordination will depend on size, type, and placement of DG. This paper explores the effect of high DG penetration on protective device coordination and suggests an adaptive protection scheme as a solution to the problems identified. Results of implementation of this scheme on a simulated actual distribution feeder are reported.

TL;DR: An embedded interaction of generators through the transmission network which is governed by the differential and algebraic equations of the apparatus and interconnects is implied, which has to be protected from abnormalities.
Abstract: They may occupy different angular positions, but all machines rotate at the same electrical speed. This close knitting implies an embedded interaction of generators through the transmission network which is governed by the differential and algebraic equations of the apparatus and interconnects. This aspect is referred to as the system behaviour. This system has to be protected from abnormalities which is the task of protection system.

TL;DR: In this paper, a control strategy for inverter-based DGs is proposed to control both voltage and frequency during islanded operation, and a protection scheme was proposed to protect both the lines and DGs during islanding operation.
Abstract: Performing intentional islanding or micro-grid operation of Distributed Generators (DGs) can improve the power system service quality and increase the power system reliability. Despite the benefits micro-grid operation can bring to the power system, many challenges and technical issues constraint its operation. This paper addresses two main challenges associated with the operation of micro-grids: voltage/frequency control and protection. The main aim of this paper is three-fold. First, a control strategy for inverter based DGs is proposed to control both voltage and frequency during islanded operation. Secondly, a protection scheme is proposed to protect both the lines and DGs during islanded operation. Lastly, both the control scheme and the protection scheme are coordinated to avoid nuisance tripping of the DGs and non-critical loads. The study is performed using a digital computer simulation approach PSCAD/EMTDC.

TL;DR: An efficient communication-based protection scheme that implements common directional overcurrent relays instead of reclosers at the line, assisted by intertripping and blocking transfer functions is proposed.
Abstract: Conventional overcurrent protection schemes for radial distribution systems usually attempt to coordinate a recloser at the beginning of the feeder with the fuses on the laterals. The integration of distributed generation in distribution systems leads to problems related to protection coordination that are difficult to be solved by applying conventional protection techniques. This paper proposes an efficient communication-based protection scheme that implements common directional overcurrent relays instead of reclosers at the line, assisted by intertripping and blocking transfer functions. The proposed protection strategy guarantees selectivity regardless of whether the generating units are connected to the network or not, and can be designed retaining either the fuse-blowing or fuse-saving philosophy. Meaningful conclusions are derived from the application of the scheme on a test distribution system.
