VEDA

VEDA2.0 is a proprietary commercial software that is designed and developed by KanORS-EMR (India). It is a powerful tool required for managing input data and for smart exploration of the results produced by TIMES models. VEDA is under continuous development, driven by a strong desire to keep increasing the efficiency and transparency of managing input and output of data-intensive models.

Brief Description

VEDA2.0 is a powerful, yet user-friendly set of tools geared to facilitate the creation, maintenance, browsing, and modification of the large databases required by complex mathematical and economic models. Also, smart exploration of the results created by such models and the creation of reports. The VEDA system is composed of two major subsystems – Browse/Items view to look at input data and Results/Reports modules to analyse the model output.


Overview of the VEDA system for TIMES modeling

Veda Tools

Data and assumptions are fed into VEDA that provides input to the TIMES code. VEDA accepts input from a variety of Excel files with different (flexible) structures that are tailored to work efficiently with data intensive models. The TIMES code works in the GAMS environment and produces text output that is read by VEDA. VEDA produces numerical and graphical (mainly via Excel) output for the user.

VEDA is under continuous development, driven by a very strong desire to keep increasing the efficiency and transparency of managing input (and output) of data-intensive models. The vision statement of VEDA applications is to take the drudgery out of modelling. The developer being its first user is a special feature of VEDA. Intimate domain knowledge has obvious advantages for software development.

The system is fundamentally biased towards large-scale multi-region models. It can certainly support small single-region models, but its real power comes into play when modelling several regions together. The primary focus of this system has been on expanding the envelope of possibilities. VEDA uses a support site and a forum to support its users.

The development of VEDA (Versatile Data Analyst) is a significant chapter in the evolution of energy system modeling tools. Originating from the foundational work on MARKAL (Market Allocation) models, VEDA's inception traces back to the period between 1994 and 1999. During this time, its developer engaged in doctoral and post-doctoral research, utilizing FoxPro to facilitate the transfer of information from Lotus and Excel spreadsheets into MUSS (MARKAL Users Support System) databases. This early work laid the groundwork for what would become VEDA.

In the year 2000, a decisive step was taken to formalize VEDA's development through the establishment of a dedicated team in India. This move marked the beginning of VEDA's transition from concept to application. Initially, VEDA served as a MARKAL shell for the SAGE (System for the Analysis of Global Energy Markets) model of the Energy Information Administration (EIA). This application demonstrated VEDA's potential to streamline and enhance the modeling process by providing a more intuitive and flexible interface for users.

The subsequent years saw VEDA's capabilities and applications expand significantly. By 2006, VEDA had evolved to support TIMES (The Integrated MARKAL-EFOM System) models, marking its emergence as the first TIMES shell. This development underscored VEDA's adaptability and its ability to cater to the evolving needs of energy system modeling.

As of February 2024, VEDA's global footprint extends to licensed users across 92 countries.
