Coordination of distributed energy resources for distribution grid reliability
Abstract/Contents
- Abstract
- Climate change concerns and economics are driving higher electrification and the adoption of distributed energy resources, such as rooftop solar photovoltaic, small scale battery storage, and new electricity consuming devices such as EV chargers, electric heat pumps, and water heaters, as part of an effort to reduce dependency on fossil fuels. Additionally, advances in information technology have enabled the grid to be increasingly observable and controllable with the widespread installation of new sensors and smart devices. While these changes have profound effects on all aspects of the power grid, we focus on the impacts of electrification and distributed renewable generation on the consumer side, leading to the rapid adoption of DERs. In particular, we look at how the increase in electrification including EV chargers, will cause significant increase in load which can lead to transformer overloading and how excess energy generated by rooftop solar and other DERs can be fed back into the grid, which can cause voltage and transformer problems. It has been projected that combating these challenges of increasing electrification and DERs would require costly infrastructure upgrades and / or the development of novel DER coordination schemes that jointly control DERs across a distribution grid, and electricity tariff structures and incentives. The controllability and flexibility of DERs, create an opportunity to coordinate their operation to reduce energy and grid upgrade costs while protecting local grid infrastructure assets such as transformers and maintaining grid reliability. However, effective integration and coordination is difficult because it requires the culmination of many consumer preferences, cyber-physical constraints, scalability, and various communication protocols and control access constraints. We use a power flow driven simulation and optimization methodology to quantify the adverse impacts of projected increases in DER penetration and electrification on distribution grids under different DER control schemes and electricity tariff structures. We describe a methodology for simulation of the grid and its devices including a quantification of the performance limits on DER coordination with two bookend controllers. A local only controller that represents the lower end of grid reliability performance for DER coordination and a perfect foresight oracle controller that represents the upper end of grid reliability performance. Then, we discuss the challenges of an implementable scheme and present a DER coordination scheme via day-ahead demand and supply power bounds that satisfies all the criteria for an implementable scheme.
