The main purpose is to introduce competitive mechanism into the power industry so as to enhance the overall management efficiency. As to the traditional vertically integrated power industry, the generation sector does not have the characteristics of natural monopoly, the removal of restrictions on production and selling can lead to liberalization. On the other hand, to alleviate the natural monopoly of transmission and distribution sectors, the use of power wheeling becomes another important strategy in liberalization of power industry. Cogeneration systems mostly have smaller capacities, and most of them are situated at the distribution systems in industrial parks. If power wheeling can be permitted in the industrial parks, it can not only serve as the transitional step of wheeling in overall system of our country, but also urge the enterprises in the industrial parks to integrate the demand of electric power and thermal energy and to establish cogeneration systems, thus to improve the overall efficiency of energy use . Focusing on the feasibility of power wheeling in industrial parks, this thesis takes Ta Yuan Cogeneration Corporation as the study case, based on the results of load flow analysis to investigates the effects of the cogenerator towards the whole system when undertaking power wheeling in industrial parks. Furthermore, the problem of how to allocate the line cost to the users of the network rationally is another important subject. This thesis, focusing on the radial distribution system that specifically exists in the traditional industrial park, proposes a wheeling cost allocation model based on distribution factors, which takes into account both the buying and selling parties in the wheeling transactions. Finally, by using this model to the practical system of Ta Yuan Industrial Park, this thesis carry out several case studies to justify the fairness and rationality of the proposed model when dealing with the wheeling cost allocation problems in industrial parks .
