| Popis: | 88 Deregulation of the electricity industry has been taking place in several countries. It will bring about significant changes in generation and transmission patterns. Customers will no longer deal with one integrated electric utility. As a result, customers will get power through wheeling. Therefore, study on wheeling cost is getting more attention in recent years. The cost of power wheeling comprises fixed and variant costs. The fixed cost means that it does not increase or decrease with the change of wheeling power. On the contrary, the variant cost means that it changes with the variation of wheeling services. This research will focus on variant cost only. One new technique, namely Buses Sorting with Ordering Method, is used to trace the flow of electricity based on the Proportional Sharing Principle. This technique does not occupy PC memory and it can run effectively for large power systems. A new approach to study wheeling cost called MVA-KM Method via applying AC power flow is proposed in this research. The proposed approach is more reasonable and valid than the MW-KM Method which is based on DC power flow. Two example systems are used to evaluate the proposed method, and the results from the proposed method are compared with that from the MW-KM Method. |
