This paper presents a sequence networks based methodology for investigating voltage unbalance in distribution networks with renewable generation. The sequence networks are derived from the original asymmetrical three-phase network, and then interconnected to study sequence voltages and unbalance propagation through the network. The approach enables to analyse the influence of line impedance, load demand and network topology on voltage unbalance caused by distributed generation in the network. The critical factors which impact the unbalance severity and the propagation mode are also identified. The approach is validated by comparing calculated sequence voltages with the results obtained by phase voltage based methodology.

“…It is clear that new models for electronically coupled DERs need to be adopted and standardized, in order to have a good approximation of fault responses. In [33,[108][109][110], the fault models for electronically coupled DERs for dynamical simulations were proposed, and validated on small systems. These models simulate DERs with high precision, but they are too complex.…”

We aim to systematically review challenges imposed by emerging distributed energy resources (DERs) to model in two basic distribution management system (DMS) online applications-power flow and short-circuit analysis, as well as to offer a systematic review of potential solutions. In the last decade, electronically coupled DERs became increasingly popular. DERs can employ a wide range of control strategies for power, current, or voltage control, in both normal and faulted conditions. Therefore, DERs cannot be modeled with the traditional PQ (load or generator bus), and PV (generator bus) bus types used for modeling synchronous and induction machines in online power flow calculations. Moreover, because fault currents of DERs are limited to predefined maximal values, electronically coupled DERs cannot be represented with traditional voltage source behind impedance models for online short-circuit calculation (SCC). However, most of the DMS software packages still use the traditional models to represent all DER types, including those that are electronically coupled. This paper shows that there will be high calculation errors in such practice, which makes the system model be an inadequate representation of the system. And this will lead to serious errors in managing, control, and operation of distribution systems. Nonetheless, potential solutions to the challenges are systematically reviewed. Finally, calculation results on a distribution test system with all DER types are used to prove the claim.

“…Although wind and solar power generation can reduce peak load demand and losses in a distribution circuit [1], these RESs may cause problems in a circuit, such as voltage regulation [1][2][3], flicker [3,4], reverse power flow [1,5], short-circuit current contribution [2,3,6,7], protection coordination [2], capacitor switching transients and harmonics distortion [2,3,8,9].…”

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.
