“…It is a 3-phase distribution system analysis power flow solver that can handle unbalanced phases. OpenDSS is commonly used to model solar on the grid because of its high-resolution time series analysis capabilities [3][4][5][6][7]. Currently available utility-standard simulation tools are not generally well suited for sequential or dynamic simulations needed to fully characterize the effects of PV output variability on distribution feeders.…”

This manual provides the documentation of the MATLAB toolbox of functions for using OpenDSS to simulate the impact of solar energy on the distribution system. The majority of the functions are useful for interfacing OpenDSS and MATLAB, and they are of generic use for commanding OpenDSS from MATLAB and retrieving information from simulations. A set of functions is also included for modeling PV plant output and setting up the PV plant in the OpenDSS simulation. The toolbox contains functions for modeling the OpenDSS distribution feeder on satellite images with GPS coordinates. Finally, example simulations functions are included to show potential uses of the toolbox functions. Each function in the toolbox is documented with the function use syntax, full description, function input list, function output list, example use, and example output.

This paper presents the situation of the photovoltaic power plants nationwide (Romania) and in particular the situation of the photovoltaic (PV) power plants in Mureş county. It also describes the minimal technical conditions that a PV power plant must fulfill before it is connected to the national grid. A particular case study consists of the impact that the PV power plant in Chirileu has on the Medium Voltage line Ungheni-Cipău and the interconnection High Voltage station in Ungheni. The case study contains an analysis of the voltage drops in predefined points, power flows with and without the PV power plant connected, respectively active power losses across the line. The study will be performed upon the photovoltaic power plant with an installed capacity of 3.2 MW connected to the 20 kV Ungheni-Cipău overhead power line and supplied from 220/110/20 kV Ungheni system station. Index Terms-impact on power system, photovoltaic power plant, power flow, voltage level.I.

“…Different penetration levels were also discussed in some papers. Each of these papers have recommended a specific location for PV panels in the feeder [5]. However, they used a very simplified model for the loads and the feeder.…”

High penetration of photovoltaic panels in distribution grid can bring the grid to its operation limits. The main focus of the paper is to determine maximum photovoltaic penetration level in the grid. Three main criteria were investigated for determining maximum penetration level of PV panels; maximum voltage deviation of customers, cables current limits, and transformer nominal value. Voltage deviation of different buses was investigated for different penetration levels. The proposed model was simulated on a Danish distribution grid, considering grid parameters and operating condition in Denmark. Three different PV location scenarios were investigated for this grid: even distribution of PV panels, aggregation of panels at the beginning of each feeder, and aggregation of panels at the end of each feeder. Load modeling is done using Velander formula. Since PV generation is highest in the summer due to irradiation, a summer day was chosen to determine maximum PV penetration for the grid.
