“…For example, in 2005 Xia et al [21] developed 9-bus and 179-bus transmission test systems that were then used by Chatterjee and Ghosh [22] (among others) to conduct transient stability studies. Gegner et al [23] propose a new method for the construction of transmission test systems.…”

An integrated transmission and distribution test system for evaluation of transactive energy designs

This study presents an open-source software platform specifically tailored to permit careful dynamic performance evaluation of transactive energy designs for end-to-end electric power systems. The platform models a centrally-managed wholesale power market operating over a transmission grid linked to one or more distribution systems, where each distribution system consists of a collection of grid-edge resources operating over a distribution grid. Test case findings are presented to illustrate the capabilities of the platform. The test cases implement a transmission system linked to a distribution system populated by households that have smart price-responsive appliances as well as conventional loads. Transactions at the distribution level are conducted in accordance with a well-known bid-based transactive energy design known as the PowerMatcher.

“…Works [7], [8], [9] provide readers more details on geographic substation placement, synthetic transmission line topology design and line parameter determination. As summarized in Fig.1, the network construction process is based on the statistics summarized from EI case, geographic relations, location-dependent load levels and generation capacities.…”

“…Until recently, there was limited work focusing on the creation of synthetic large-scale power system models using publicly available data to mimic the full complexity of today's electricity grids for energy economic studies. Our previous works [7], [8], [9] presented a methodology to create entirely fictitious synthetic power system networks that capture structural and functional characteristics of actual power grids 1 . To enable greater innovation on electricity markets, this paper aims to augment the synthetic power system networks with generator cost data, and thus provides realistic test cases for energy economic studies without revealing any sensitive information.…”

Due to information confidentiality issues, there is limited access to actual power system models that represent features of actual power grids for teaching, training, and research purposes. The authors' previous work describes the process of creating synthetic transmission networks, with statistics similar to those of actual power grids. Thus, this paper outlines a systematic methodology to augment the synthetic network base case for energy economic studies. The key step is to determine generator cost models by fuel type and capacity. Based on statistics summarized from the actual grids, two approaches are proposed to assign coefficients to generator cost models. To illustrate the proposed creation procedure, we describe the construction of a synthetic model for Electric Reliability Council of Texas footprint. Simulation results are presented to verify that the created test system is able to represent the behavior of actual power systems.

“…Authors in [20] reported some initial study results on the statistics of transmission line parameters. The substation placement method and transmission lines assignment based on population and energy data in [21] uses the methodology introduced in [22], [23], where they employ a clustering technique to ensure that synthetic substations meet realistic proportions of load and generation. [24] addressed the need for synthetic large-scale system dynamic models for transient stability studies such as wide-area damping control in [25], [26] and dynamic control allocation for damping of inter-area oscillations in [27].…”

Transformers and transmission lines are critical components of a grid network. This paper analyzes the statistical properties of the electrical parameters of transmission branches and especially examines their interdependence on the voltage levels. Some interesting findings include: (a) with appropriate conversion of MVA rating, a transformer's per unit reactance exhibits consistent statistical pattern independent of voltage levels and capacity; (b) the distributed reactance (ohms/km) of transmission lines also has some consistent patterns regardless of voltage levels; (c)other parameters such as the branch resistance, the MVA ratings, the transmission line length, etc, manifest strong interdependence on the voltage levels which can be approximated by a power function with different power constants. The results will be useful in both creation of synthetic power grid test cases and validation of existing grid models.
