As the penetration of Distributed Energy Resources (DERs) increases, it becomes critical to model these resources adequately in bulk power system (BPS) operation and planning studies. Adequate in this context refers to capturing the characteristics of the distribution system to the required degree such that reasonable estimates about BPS stability can be ascertained. Historically, performing such studies have been limited due to the unavailability of software capable of executing high fidelity simulation at the required scale on personal workstations i.e. not having to resort to high performance computing resources. In this paper, we present TDcoSim, an open source software that allows user to perform large scale high fidelity simulation for BPS planning and operation studies and (a) outline the necessary details required to build such software, (b) present the practical challenges faced during the development of TDcoSim.

This paper proposes a model of grid-connected photovoltaic (PV) system with low voltage ride through (LVRT) characteristic in MATLAB/Simulink based on dynamic phasor approach. Unlike all PV system models available in MATLAB/Simulink using detailed model with small capacity, the proposed model focuses on control loops of PV system to simulate a large capacity system that is appropriate for voltage stability analysis of power system installing high penetration level of PV generation. An intuitive and convenient tool for adjusting the LVRT characteristics of the PV system is also developed. The effectiveness of dynamic phasor model and the impact of the LVRT characteristic of the PV system on voltage stability are examined through MATLAB/Simulink simulations conducted on IEEE 9-bus test system. The simulation results provide an insight of how the system integrated with a large PV generation behaves under the disturbances. It also points out that the LVRT of the PV system is very important to the power system voltage stability.

“…Not unbeknownst to engineers and academics, both bridge and filter topologies affect inverter performance and dynamics; however, in most stability or power researches, authors use standard models (Wu et al (2016)) which do not translate those dynamics nor comprehensively model filter or switching effects (Kotian and Shubhanga (2016)). These models are known to sufficiently resemble real-world behavior in a very strict set of conditions -specially static behavior; however, as the stability studies get more sophisticated, inverter dynamics play a big role in the end result and conclusion.…”

Given the increasing penetration of photovoltaic and battery-powered systems in macro and microgrids, efficient and reliable modelling of the inverters for studying the stability of such systems is paramount. In the current academia standard, generic inverter models, which do not coherently represent inverter behavior nor consider inverter topology and filter, are used - undermining the presented results. This paper presents a thorough and comprehensive per-unit modelling of inverter systems based on a strong mathematical foundation. This modelling is compatible with Equivalent Phasor techniques, generally used for synchronous machines, which allow simulation and study of stability of mixed systems where both technologies are present.
