Resumo: |
After implantation of the new economic model for power systems, a fair remuneration strategy of transmission companies has become a matter of great importance. This remuneration should be performed by system users, who must pay proportionally to its network usage. However, there is still no consensus about wich is the best criterion to be adopted to allocate these costs. The most widely used methods take into account the power ows only at normal operating conditions. however, it is recognized that the transmission system is planned and operated to accommodate power also at contingency scenarios, which requires additional transmission capacity. Moreover, part of the idle capacity is due to the characteristics of network investments and uncertainty in relation to demand. Thus, the costs allocated by these methods may not re ect the actual usage of the system. In this context, this work presents a transmission cost allocation method that takes into consideration all these network characteristics. The total costs are decomposed into three components, each of these associated with a part of the transmission capacity of the system and its function. These costs are then allocated based on their system usage in diferent operating scenarios. To validate the proposed method, tests are performed on small and medium power systems. Comparisons are established with some methods more used in the literature, where it is observed that the proposed method provides complete consistency with the expected results for the problem. It was also found that this method offers subsidies to consumers allowing them to define their security requirements. |
