CLOSED FORM ESTIMATION OF BOUNDARY VALUES IN ELECTRICAL DISTRIBUTION NETWORKS

摘要

The paper deals with the problem of estimating operating quantities in low-voltage distribution networks. The load is considered to be a stationary process and the proposed method gives the first two moments of current and voltage at an arbitrary node of the network. Boundary values that must not be exceeded with a given probability can thus be easily obtained. Moreover, the method calculates the estimates in a closed form, parameterized by coefficients of correlation between customers' loads. Hence, there is no need to recalculate the whole network if different coefficients are used.
