Structural analysis of variation of electricity transmission marginal costs
Structural analysis of variation of electricity transmission marginal costs

Summary/Abstract: The paper presents a surface model of the accounting costs of electricity transmission over the 220 kV and 400 kV networks. A structural analysis of marginal costs variation was carried out. Variogram functions (isotropic, directional variogram, variograms roses) were used to build the model. The model describes well the considered phenomenon, i.e. the area and time variation of marginal costs, and has great potential in the electrical power sector, especially in the context of the development of market mechanisms in electric energy trading. The model has made it possible to observe the existing tendencies in cost (directional and time) variation, which is useful for setting electricity transmission tariffs correctly stimulating the behaviour of the electric power network users – the electricity suppliers and consumers.
