Abstract: (15 Views)
The increasing frequency of severe weather phenomena has significant impacts on power distribution systems and can lead to system failure and power outages for consumers. In this regard, the formation of microgrids and their operation in islanded mode has been proposed as a resilient solution to address major faults in the distribution system. The resilience of the power system refers to the network's ability to reduce the negative effects of rare and high-impact events. With the growing penetration of distributed generation, the formation of microgrids, especially with the use of distributed generation, has been suggested as an effective method to restore critical loads in the distribution system when facing such events, in order to enhance system resilience. This research presents a new model for forming microgrids, in which power losses and voltage constraints are considered within the balance of power and operational feasibility. The introduction of binary variables to represent network reconfiguration status, along with the use of nonlinear equations to model the precise power flow, transforms the microgrid model into a Mixed-Integer Nonlinear Programming (MINLP) problem. In this paper, a linear approximation method based on iteration is proposed to solve the MINLP, and its accuracy is ensured through the iterative convergence process. The numerical results obtained based on the standard IEEE 33-bus distribution system demonstrate the effectiveness of the proposed method.
