Abstract: Accurately modeling power system loads is essential in simulation-based power system planning and operation studies. Since large industrial facilities such as petro-chemical plants and paper mills are major power system loads, they must be modeled properly. Utilizing the concept of the template-based load modeling technique for industry facilities, this thesis investigates the modeling of paper mills for power system dynamic studies. A systematic approach with representative data is established for constructing equivalent dynamic models of the Kraft type of paper mills. Case studies demonstrate that the proposed model can capture the dynamic behavior of paper mill facilities adequately and accurately. This thesis also investigates the modeling of DC motor drives and their collective dynamic responses for system dynamic studies. The DC drive is one type of elementary load, the modeling of which has not been fully studied in the past. It is also a major load component in paper mills. This work develops an equivalent dynamic model of DC drives, and a model aggregation technique. Simulation results demonstrate the accuracy and usefulness of the proposed model.
