The necessity for the utilization of microgrids emerges from the integration of distributed energy resources, electric vehicles, and battery storage systems into the conventional grid structure. In order to achieve a proper operation of the microgrid, the presence of a microgrid control system is crucial. The IEEE 2030.7 standard defines the microgrid control system as a key element of the microgrid that regulates every aspect of it at the point-of-interconnection with the distribution system, and autonomously manages operations such as the transitions of operating modes. In this paper, a microgrid control system is developed to achieve real-time monitoring and control through a centralized approach. The controller consists of a centralized server and advanced field units that are also developed during this work. The control functions of the centralized server ensure the proper operation during grid-connected and island modes, using the real-time data received via the advanced field unit. The developed server and the field unit constitute a complete system solution. The server is composed of control function and communication, database, and user interface modules. The microgrid control functions comprise dispatch and transition core-level functions. A rule-based core-level dispatch function guarantees the security of supply to critical loads during the islanded mode. The core-level transition function accomplishes a successful transition between the operation modes. Moreover, a communication framework and a graphical user interface are implemented. The presented system is tested through thecases based on the IEEE 2030.8 standard.

Design of a Centralized Microgrid Controller in Compliance with IEEE 2030.7 Standard Pouraltafi-Kheljan, Soheil; Göl, Murat; Department of Electrical and Electronics Engineering (2021-9-10) With the incorporation of renewable distributed energy resources and electric vehicles and battery storage systems into the conventional grid structure, the need for a microgrid and its control is emerging. IEEE 2030.7 Standard defines the Microgrid control system as a key element of microgrid regulating every aspect of it at the point-of-interconnection (POI) with the distribution system and autonomously manages operations such as transitions of operating modes. This system consists of control functions, w...
Cloud-based Optimal Energy Scheduling of Photovoltaics and Electric Vehicle-integrated Community Microgrids Zehir, Mustafa Alparslan; Tufan Dogan, Osman; Merdanoglu, Hakan; Yakici, Ertan; Duran, Serhan; Can Akyildirim, Hayri (2022-01-01) © 2022 IEEE.Community microgrid is one of the promising pathways to achieve higher levels of penetration of distributed generation from intermittent renewables and energy storage, further electrify heat and transport and enable active energy customers. Optimal energy scheduling of wide range and large number of flexible asset, using operational information from stakeholders (such dynamic pricing rates) and relying on customer preferences has been a processing power intensive major challenge. The inconsisten...
Operational Optimization of an Agricultural Microgrid Brown, Paul D.; Göl, Murat (2022-01-01) A demonstration agricultural microgrid containing solar photovoltaic (PV), battery storage system (BSS) and multiple water pumps and reservoirs is presented. A mathematical model of the cost of operating the demonstration microgrid is developed. The mathematical model includes hybrid inverter source switching and BSS charging modes in addition to power balance and inter-period energy and water-level coupling. Electricity pricing and irrigation water use efficiency are allowed to vary by time of day. The mat...
Numerical investigation of a stand alone solar hydrogen energy system effects of PEFC degradation Ender, Ozden; Tarı, İlker (null; 2015-08-12) An existing stand-alone solar energy system producing hydrogen for energy storage is numerically investigated focusing on the degradation of Polymer Electrolyte Fuel Cell (PEFC) and its effects on the overall performance of the system. The system consists of Photovoltaic (PV) panels, polymer electrolyte based electrolyzers, H2 and O2 storage tanks and a commercial PEFC stack. A PEFC is numerically investigated both as new and as degraded (for about two years). Using a variety of observed degradation pattern...
Sizing of Photovoltaic-Wind-Battery Hybrid System for a Mediterranean Island Community Based on Estimated and Measured Meteorological Data Sadati, S. M. Sajed; Jahani, Elham; Taylan, Onur; Baker, Derek Keıth (2018-02-01) Deploying renewable energy systems (RES) to supply electricity faces many challenges related to cost and the variability of the renewable resources. One possible solution to these challenges is to hybridize RES with conventional power systems and include energy storage units. In this study, the feasibility analysis of a grid-connected photovoltaic (PV)wind-battery hybrid system is presented as a microgrid for a university campus-scale community on a Mediterranean island. Models for PV and wind turbine syste...
