IEEE 2030.7 standardına uygun bir merkezi mikro şebeke denetleyici tasarımı

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, which can be layered into the high, core, and low-level functions. The core-level functions comprise dispatch and transition functions, while the high-level functions include supervisory operations. In the proposed approach, a system is developed to achieve real-time monitoring and control of a microgrid through a microgrid central controller that ensures the proper operation of grid-connected and island modes. The microgrid system includes photovoltaic units, electric vehicles, battery storage systems, and bi-directional grid connections. 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 mode. As a high-level function, the optimal operation of the microgrid in grid-connected mode is found by a model predictive control (MPC) based algorithm that incorporates the future reference information of the generation and load forecasts into the battery storage systems and vehicle to grid and vice versa control problem. Moreover, a communication framework and a graphical user interface are implemented.
