Substation Automation and Optimization of Distribution Circuit Operations
Enhancing substation controls to maximize use of renewable and distribution energy resources
This project was completed in March 2019. The final report is in process for publication. UCI completed the development and simulation, in partnership with SCE, of the GMC for enhanced substation control. The GMC showed optimal control of DERs on the distribution feeder while using the IEEE 2030.7 microgrid controller standard. UCI will create a hardware-in-loop test for the configuration using industry standard substation equipment. Although the hardware test was not funded through the grant, UCI is committed to validating the research results for purpose of grid modernization and informing stakeholders. The research results from this project informed the top power technology vendors, such as GE, Siemens, and Schneider Electric. A retail market was simulated and various tariffs were evaluated to determine benefits to developers, utilities, and grid stability.
This project developed a Generic Microgrid Controller (GMC) to allow electrical substation control over grid assets, including generation resources, energy storage, and controllable loads. The GMC improved grid management at the distribution level. The team assessed different tariffs and interconnection agreements for a portfolio of scenarios to address the participation of DERs in the market. In addition, a fictitious retail/distribution market was developed and assessed.
The controller helps optimize dispatch of the available resources on the distribution system, which lowers operation costs by dispatching and utilizing available assets so that resources will be neither stranded nor under-utilized.
The controller provides visibility into the distribution system and will enable the operators to identify any issues quickly and respond to maintain system reliability.
Enhancing automation and control capabilities of a substation allows for quick resolution of safety issues. Controlling load further allows for ensuring that the critical loads are being served in case of an emergency.
