Abstract
In this paper, a simulator for assessing the possibility of PV integration to the medium voltage distribution network is developed. The PV location and peak power are defined in advance. The simulator is based on sequential Monte Carlo simulation with various possible uncertainties such as photovoltaic production and load. In addition, the sequential simulation enables detection of period when the network constraints are violated. For this analysis, time series of essential variables such as PV system production and load are modeled. Based on the results of power flow calculation, probability distributions of the voltage at various nodes, the loads on individual lines as well as the probability of network constraints exceeding are determined. Depending on the network constraints, possibility of connecting the PV system to the network at the desired location is assessed. The power flow calculation is executed by using the OpenDSS simulator, while the input time series are prepared in Matlab. The method presented in this paper is tested on IEEE 33 distribution test network.
