11 10.2.1 Voltage Regulating Devices Consensus that voltage regulating devices should be “unlocked” (float) within iterative methodology, but no regarding process and timing of implementation. IOUs recommend each IOU models voltage regulating devices in initial systemwide rollout as it did for Demo A and work with software vendors (CYME) to include this functionality. Other WG members recommend IOUs work with software vendors to develop this functionality before initial systemwide rollout. Non Consensus 12 10.2.2 Operational Flexibility ICA values should be calculated with and without the No Reverse Flow at Supervisory Control and Data Acquisition (SCADA) Devices constraint for initial systemwide rollout (see section 9), which is how the IOUs modeled these scenarios in Demo A per ACR requirements. Consensus 13 10.4 Treatment of PreExisting Conditions ICA should be limited by preexisting conditions (i.e., display an ICA value of zero) when adding Distributed Energy Resources (DER) degrades pre existing condition; ICA should not be limited by preexisting condition when adding DER improves preexisting condition. Consensus
learned, and the IOUs’ recommendations on the methodology calculation and next steps regarding implementation of LNBA. On March 8, 2017, the LNBA Working Group filed their LNBA Final Report, which (1) summarized the Working Group’s recommendations; (2) provided support for a Commission decision on Demonstration Project B; (3) provided input for the Commission to develop an implementation plan for further development of LNBA; and (4) outlined refinements for the Commission to address before the adoption and full systemwide rollout of a LNBA methodology and tool. In Table 2, we summarize the LNBA Working Group Report Recommendations for Commission Policy Guidance: Table 2. LNBA Working Group Report Recommendations for Commission Policy Guidance Item No. Report Section Recommendation (Summary) Consensus/ 1 3.1 Demo B Compliance with ACR Formally recognize that Demo B projects/reports are in compliance with ACR requirements. Consensus 2 3.1 LNBA Provisional Use Demo B methodology is appropriate for provisional use in Integration of Distributed Energy Resources (IDER) pilot, DRP Demo C, and Deferral Framework (recommendation reiterated in Section 3.2). Consensus 3 3.2 LNBA Use Cases: Public Tool; Deferral Prioritization Demo B methodology can be used for two use cases: 1) public tool/heat map; 2) prioritizing candidate deferral projects. Consensus consensus
initial systemwide rollout in the same way they modeled these scenarios in Demo A. IOUs shall publish in their downloadable datasets the specific criteria violations (e.g., thermal, voltage, safety, protection) associated with the limiting ICA value. Each IOU shall model voltage regulating devices in initial systemwide rollout as it did for Demonstration Project A. Pacific Gas and Electric Company and Southern California Edison Company are directed to work with software vendors to enable voltage regulating devices to be “unlocked” (float) within iterative methodology, and shall report on progress on such work in Interim Reports. Longterm refinement discussions can also consider how to implement such methodology after initial systemwide rollout is complete. ICA shall be limited by preexisting conditions (i.e., display an ICA value of zero) when adding Distributed Energy Resources (DERs) degrades preexisting condition; and 2) ICA shall not be limited by preexisting condition when adding DERs improves preexisting condition. Investor-Owned Utilities shall document their methods for handling pre-existing conditions in Interim Reports. The IOUs shall maintain technologyagnostic approach to calculating ICA values as employed in Demo A that does not make assumptions on technologyspecific DER portfolios or response to California Independent System Operator dispatch. The IOUs shall continue to standardize a common mapping structure and mapping functionality while using what was developed for Demo A for an initial systemwide rollout. The IOUs shall display the following attributes in their online ICA maps: Circuit ID; Circuit Load Profile; Section ID; Voltage (kV); Substation ID; Substation Load Profile; System; Customer class proportions on circuit; Existing generation (MW); Queued generation (MW); Total generation (MW); Hosting capacity for uniform generation (MW); Hosting capacity for uniform load (MW); and Hosting capacity for generic PV system (MW).
