ABSTRACT

Nowadays, information plays a major role in every power systems, especially Microgrids (MGs). As MGs become more common in power systems, it feels more necessary than ever to make a communication link between MGs and the main grid, and between MGs. In this manner, communication infrastructure in Multi Microgrid Clusters (MMC) may be used for many applications of MGs. For instance, Power Quality (PQ) is becoming more and more important in electricity systems, as a result of increasing in the number of converter- based devices and stochastic nature of power generation and consumption in MGs. Challenges in PQ, like voltage drop, become more and more serious as single phase loads, such as Electric Vehicles (EVs), increase in the number. On the other hand, stochastic nature of power generation, like wind power and photovoltaics makes the situation worse. In this regard, improving PQ, like dealing with harmonics in the grid, is a challenge for today’s Smart Grids (SGs) and MGs. For this especial case, communication could be used to improve PQ indices. Improving PQ in distribution level is possible in case that both the user side view point and the power system point of view are considered. This means that not only advantages of improving PQ for the power system should be considered, but also end- users’ concerns (both financial benefits and technical issues) is important. Using Internet of Things (IoT) in energy systems introduces new horizon that every object in the system could transact information with the whole system. Collecting information from the end- users is possible by using Advance Metering Infrastructure (AMI). In this project, the assessment of PQ in the framework of IoT is studied. To do so, advanced PQ solutions both for a single MG and MMC are aimed. Hence, by using IoT framework and measuring required information by Smart Meters (SM), not only power can exchange between MGs, but also valuable information of each MGs could be transferred between MGs and end-users. Aside from this, collecting information from heterogeneous sources is an ongoing challenge for the IoT. In this regard, the IoT Microgrid Living Laboratory will provide a case-study for the project.
