Popis: Southern California Edison (SCE) is in the process of implementing Smart Grid applications as part of an ongoing grid modernization effort to improve reliability and asset utilization, avoid DER-caused problems, and timely demand response to market and/or other signals. How many sensors are needed, where to deploy them and what data do they need to provide are questions that have a considerable impact on the effectiveness of these applications and significant economic consequences for SCE and other utilities. This paper presents a stochastic methodology that allows utilities to quantify the accuracy of DSSE results for simulated sensor placement and operational forecasting scenarios. We applied this methodology to six real-world distribution circuits located in SCE's service territory to inform the deployment of sensors and operational forecasting that yield sufficiently accurate DSSE results with respect to achieving optimal and violation-free execution of the Volt-Var Optimization (VVO) Smart Grid application.
