  • Quanta provides services to utilities to support their goals for improving distribution system reliability and performance using several methods to analyze data, plan and execute strategy. One of the leading industry practices is to utilize the utility’s distribution system analysis software to perform reliability studies using computational models. These studies encompass four main steps: 1. Assessing the existing reliability of distribution circuits. 2. Identifying and prioritizing cost-effective projects for reliability improvement (e.g., underground cable replacement, recloser installation, etc.). 3. Estimating expected reliability at circuit and protection/switching zone level. 4. Conducting benefit-cost analyses. Utilities may elect to compare the results from their existing methodology and tool for distribution reliability analysis versus using computational power flow models.
  • Distribution systems planning is a vital activity for the successful modernization of the grid. Modern distribution planning is expected to become an even more complex activity, largely due to the need to integrate DER and new technologies. Grid Performance Planning is the foundation of a modern distribution plan and it combines forecasts of both loads and DER, including weather normalization, transformer loading, feeder loading, urban re-development, regression models, and spatial land-use models.  Quanta Technology has assembled a team of leading experts from the utility industry and developed state of the art tools to deliver a rigorous and comprehensive approach to address modern distribution planning system challenges. 
  • Quanta Technology performs hosting capacity studies to determine the ability of a utility to accommodate and integrate future distributed energy resources (DER) on its grid. The results of these studies are used to develop hosting capacity maps for the utility’s service territory and its distribution feeders. In general, hosting capacity analysis considers the effect of DER proliferation, specifically photovoltaic distributed generation, on thermal limits and voltages of distribution feeders.  We also have experience with hosting capacity studies that consider additional variables in creating develop hosting capacity maps; these variables may be incorporated progressively into the calculation process to increase result accuracy and comprehensiveness. Quanta Technology also supports our client partners with creating general guidelines that identify areas of the distribution system that are more vulnerable to the potential effects of DER adoption based on further analysis of capacity maps. We can also support updates to hosting capacity maps, periodically and automatically, to account for actual changes in DER penetration levels (driven by new interconnection requests), changes in system configuration, customer load growth, etc.
  • Quanta Technology has extensive industry experience conducting Distributed Generation (DG) integration and planning studies for Transmission and Distribution (T&D) systems, including identifying and evaluating the severity of impacts and proposing mitigation measures. Our team performs interconnection, impact and engineering studies (steady state, dynamic and transient analyses, protection, power quality, insulation coordination, arc flash, etc.) of DG and battery energy storage plants for many major utilities and developers. We work with major solar PV inverter manufacturers, wind turbine vendors and energy storage suppliers to develop and verify computational models of emerging DG technologies for use in various transient analyses. We also review and update utility standards, guidelines and procedures for DG interconnection to T&D systems.
  • Load forecasting in now part of grid performance planning which is the foundation of a distribution plan. Without a good load forecast, it is likely that unnecessary projects will be funded and needed projects will go unfunded. Our experts have experience in all aspects of load and DER forecasting including weather normalization, transformer loading, feeder loading, urban re-development, regression models, and spatial land-use models. We have helped many utilities in the U.S. and around the world refine forecasts, develop forecasts, and institute improved load forecasting and grid performance.
  • Quanta Technology understands the challenges of operating a safe and reliable electric grid, and realizes that due to the proliferation of distributed energy resources, such as solar PV and battery energy storage there may be unintended consequences resulting from the time-varying impacts of these technologies. Using our experience and expertise in this area, we can analyze the grid using computational models to look at steady and transient impacts from all the devices connected to the grid. This includes protection analysis that looks closely at frequency and voltage ride through, assessing the impact of islanding conditions on protection systems and DG operation, evaluating the severity of Temporary Over Voltages (TOV), and studying how sudden connection / disconnection of DG plants affect T&D system operation and protection systems.
  • Optimal volt/VAR control is critical for ensuring utility customer power quality and system efficiency. The proliferation of intermittent distributed generation such as photovoltaic and wind introduces new challenges such as rapid voltage fluctuations and reactive power flow variations that need to be studied using computational models and simulation tools. Quanta Technology has extensive experience in this area and can aid utilities to solve these issues via the implementation of modern volt/VAR control schemes and technologies.
