Abstract

In order to further improve the refinement of power grid planning, improve the quality of enterprise operation and economic benefits, a power grid planning method that considers the uncertainty of source and load is proposed in view of the uncertainty of distributed photovoltaic output and load forecasting. First of all, in view of the uncertain characteristics of distributed photovoltaic output, the concept of "photovoltaic output shielding factor" is innovatively proposed, and a probability distribution model of its daily and seasonal characteristics is established to analyze the spatial correlation of photovoltaic output. Then, on the basis of considering the investment cost of new lines, the cost of network loss, and the loss of light abandonment, a grid planning model considering new energy access is established. Finally, an empirical analysis is carried out through a typical power grid, and the results show that the model and algorithm proposed in this paper are effective and feasible.
