Participation of distributed energy resources in the load restoration procedure, known as intentional islanding, can significantly improve distribution system reliability. Distribution reconfiguration effectively alter islanding procedure and thus provide an opportunity to supply more demanded reduce losses. In addition, high-impact events such hurricanes earthquake may complicate restoration, due disconnection from upstream grid or concurrent component outages. This paper presents a...
Although natural disasters have recently imposed enormous damages to power system infrastructures, resilience enhancement through hardening measures is not usually compensated in conventional planning. In this article, a framework proposed enhance the of distribution systems against earthquakes. particular, it focuses on substations’ retrofit whose failure can affect system, imposing outages customers connected it. A knapsack based heuristic method, which considers bus configuration...
This paper proposes the idea of independent models a microgrid (MG) based on operation modes. In grid-connected operation, optimal power flow is proposed to minimize generation cost. A new decision variable was introduced represent MG as an equivalent unit from viewpoint upstream network. island contingency condition considered and reliability improvement through load restoration proposed. performance index model MGs small self-adequate islands in contingency. The main distinction between...
Intentional islanding operation (IIO) is a feasible solution to improve the reliability of active distribution network (ADN) by supplying critical loads through local DG when fault occurs. Aiming at this goal, new two‐stage methodology proposed supply based on cost‐effective improvement. In first stage, interruption cost as load priority and ON/OFF status switches are considered binary decision variables. Therefore, IIO mixed integer linear programming (MILP) problem minimise cost. At second...
Earthquakes and other natural disasters have caused significant damages to power systems, indicating the necessity enhance system resilience. This paper proposes a risk-based resilience enhancement framework against earthquakes that considers their stochastic nature. The proposed supports decision-making of distribution operators (DSOs) for retrofitting substation components underground cables consists four phases, namely earthquake modeling, vulnerability assessment, risk enhancement. An...
In recent years with growing concerns over carbon emission and uncertainties in fossil fuel supplies, there is an increasing interest clean renewable electrical energy generation. Among various sources, wind power currently the fastest form of electric The size farms requires system stability analysis including dynamic models Nowadays, most widely used generator type for units above 2MW doubly-fed induction machine. Detailed machines are well known but efficient simulation entire systems...
