Comparative Analysis of Distribution Network Cost Allocation Alternatives

Guarizi Rodrigo Delfim, Lotero Roberto C., London Joâo Bosco A.

Transactions on Environment and Electrical Engineering

2023

Vol. 5, No. 1

1--8

This paper presents a comparative study among methods of allocation of fixed costs in Distribution Networks (DNs). The application of these methods allows obtaining distribution use-of-system charges. Three pricing mechanisms composed of two part tariffs are evaluated. In the three mechanisms, the first part is obtained by the Long Run Incremental Cost (LRIC) method. The second one is determined by the following methods: Postage Stamp (PS), MW-Mile (MWM) or Ramsey-Boiteux (RB). The characterization and comparison of each method are performed from the point of view of regulatory principles that define guidelines on network pricing. The results allow identifying the adherence of the methods in compliance with the regulatory principles. Conflicting character between different principles is observed. The methods are tested and validated in the IEEE13-node distribution network. A study along these lines points to the proposition of new alternatives in pricing the use of DNs in the face of the growth of Distributed Energy Resources.

Transport service execution costs in the whole-vehicle road transport in complex transport cycles

Wasiak M., Jacyna M.

Companies compete not only on price of offered products and services, but also on the quality, including the time of delivery of the product or service implementation. Contemporary logistics solutions, ensuring high utilization mileage of means of transport, cause, that in transport complex transport cycles are increasingly common. In these cycles as opposed to a simple transport, cycles are realized many transport tasks. The paper presents the classification of the costs of implementing of transport processes in road transport. Taking into account the different cost sharing criteria was proposed their general classification. Were identified means of transport parameters that have the most significant impact on the level of costs in transport. Then, assuming that in one transport cycle can be realized many transport tasks were presented analytical dependences on the implementation costs of transport cycles, as well as the implementation costs of individual transport tasks. Presented in the article approach can be used to calculate costs of implementing full truck transport tasks performed both in complex and simple (special case) cycles. Types of costs in road transport, general classification of costs in the road transport, vehicle parameters affecting the level of direct costs of transport, principles for determining the cost of road transport carriage are presented in the paper.
