Abstract

Most existing demand response or management algorithms require a dedicated communication infrastructure to coordinate actions of electricity users. However, the necessary communication infrastructures may not be available in many low-voltage (LV) networks around the world. On the other hand, implicit information on the state of the network is readily available at all times via measurements. In this paper we propose a stochastic modelling approach to estimate aggregate network demand from local voltage measurements at each household using a gamma distribution. The model suggests a linear relationship between the expected value of network demand and voltages at households in the network. We pr..
