“…Overloading and overvoltages are the most common indicators utilized to calculate the HC of a distribution system ( [3], [4], [5] and [6] are some examples). It is generally accepted that RES relieve the network loading if the penetration level is low.…”

This paper proposes a comprehensive set of performance indicators that should be used when evaluating the hosting capacity of a system. Descriptions are given for the most relevant phenomena and how they should be quantified and measured. The suggested time resolution for the data has been 1 hour, 10 min and 3 s, based on what is available already in standard meters. The use of 100, 99 or 95percentile values have an impact on the hosting capacity, and there is a need for further discussion with regards to the selection of statistical limits.

“…A simple rule adopted in the United States consists of allowing the connection of PV generators without detailed investigation if the total PV peak power is lower than 15% of the feeder peak load . However, some feeders may accommodate more or less generation than 15% of the penetration level because it depends on factors such as feeder length, short‐circuit level, PV location, and operating practices . In Reno and Broderick, a study quantifies the accuracy of the 15% limit in 40 real distribution systems.…”

Summary The recent changes in distribution systems have challenged utilities to assess the unprecedented volume of photovoltaic (PV) generator connections, which can result in adverse technical impacts from voltage rise and conductor overload. Therefore, a fast and effective way to analyze a distribution system's capacity to host new PV generators is crucial for the utilities. Usually, the connection assessments are based on repetitive power flow and short‐circuit calculations, and even though these analyses can be accurate, they require a steep increase in person‐hours and processing time. A simpler way to identify the hosting capacity of distribution systems to the connection of new PV generators is the adoption of connection assessment tools that, if properly designed, allow utility engineers to evaluate quickly if a new PV generator can be connected or not. This work proposes a connection assessment tool based on a fast screening approach that allows utility engineers to graphically analyze if a rooftop PV can be connected to a distribution system without causing adverse impacts. Tests of the proposed method are performed in two real distribution systems, attesting to its efficiency.

“…These tools can help evaluate power system phenomena, such as voltage regulation, fault study, switching transients and harmonics analysis. The simulation tools can also be used to perform the feasibility studies of operating wind turbines and PVs in a distribution system [10,11], analyze the stability of a distribution system with wind and solar power [12,13], determine the maximum penetration or hosting capacity of wind turbines and PVs [14][15][16], evaluate the performance of wind turbine and PV control methods [17,18] and investigate the effects of energy storage systems [19][20][21] and reactive power sources, such as capacitor banks, static var compensators (SVCs), static synchronous compensators (STATCOMs) [19,22,23] and dynamic voltage restorers (DVRs) [24] to a distribution system having wind and PV generators.…”

This paper develops a distribution circuit multi-time-scale simulation tool for applications in wind turbine and photovoltaic (PV) integration analysis. The proposed simulation tool developed in MATLAB TM includes several distribution circuit components, such as voltage sources, distribution lines, transformers, loads, capacitor banks, wind turbines and PVs. Each equipment consists of three models for simulations in three different time scales, i.e., steady-state, electromechanical transient and electromagnetic transient models. Therefore, the proposed tool is able to perform a long-term simulation involving power system phenomena spreading across time scales. The test circuits employed to perform multi-time-scale simulation in this paper are modified from the IEEE four-node test feeder. The simulation scenarios include wind speed and solar irradiance ramp up and down; a capacitor bank is energized and de-energized; and a single-line-to-ground fault occurs and clears itself. The simulation results show that the proposed tool is capable of evaluating power system phenomena spread across time scales.
