“…New technologies and types of customer demand [2][3][4] require a new model of distribution network planning. We already showed [5] what impact elastic demand can have on distribution planning. Direct load control is similar, but in this case distribution utility should know in advance what price customers will pay for delivery.…”

Distribution network development planning is a complex task due to the size of a typical distribution network, the interconnectivity of its elements and the presence of various uncertainties. This planning process becomes even more complicated due to the constant pressure to reduce distribution network capacity reserve, operation and maintenance cost, and to postpone the capital investments as far as possible. Recent technological and organizational changes in the electric industry sector have had an influence on the operations and planning objectives of distribution network systems. New technologies and customer demand types require new paradigms of distribution network planning and operations. A corresponding model in support of these new paradigms should not include only the load forecast, but economic analysis, risk assessment and the impact of the new technologies. In this paper, we propose a model for distribution development planning with direct load control, distributed generators and optimal distribution capacity expansion.

In today’s society, sustainability has become a key theme, and utilizing renewable energy is part of sustainability. Under the high proportion of renewable energy access, the conventional grid is gradually shifting to an active and distributed structure, which makes the existing cost apportionment method of transmission and distribution projects unable to match the actual situation. Reasonable apportionment of the costs of different voltage levels is the basis for the evaluation of transmission and distribution projects and is important for the formulation of transmission and distribution tariffs, which in turn have a significant impact on the development of renewable energy. To this end, this paper takes China’s power system as the research object and firstly analyzes the impact of the activization of the grid on the cost apportionment of transmission and distribution projects and then the inadequacy of the existing cost apportionment, which only considers a single factor and part of the cost which should be apportioned downward is still borne by this voltage level, and then combines the activation and the inherent characteristics of the power grid to extract the multiple factors to be considered for cost apportionment, and at the same time takes into account the reverse direction of the power trend, and divides the cost apportionment into two scenarios. The cost sharing model of transmission and distribution projects based on multiple apportionment factors is established. Finally, the feasibility and applicability of the model are verified by the examples of linear and reticulated grids, and the cost sharing results obtained by this method and the traditional method are compared. Using this method for the cost sharing of transmission and distribution projects, lower voltage levels will share more costs, and higher voltage levels will share fewer costs. The results show that the inclusion of the factors affecting cost sharing in the case of an active grid is more in line with the development trend of the new power system; the cost apportionment method based on multiple sharing factors makes the results fairer; and the inclusion of the power trend conduction relationship in the sharing process reflects the essential attributes of the grid. This is conducive to improving the operational efficiency of the power grid and promoting the long-term sustainability of the power system.
