California Rule 21 Solutions

California Rule 21 by the California Public Utilities Commission mandates the interconnection standards for a select set of renewable generators. These interconnection requirements would require Inverters to support IEEE 2030.5 and need to connect to Utility SCADA Systems directly or through an Aggregator initially for monitoring purposes and later for control as well. The requirements also mandate compliance to cyber security requirements as specified by the SIWG and in the CSIP.

ASE has combined its over 35 years of expertise in working with utilities and OEM’s to design a secure and cost effective solution to meet these interconnection standards. Further ASE has partnered with its parent company Kalkitech and its Energy IoT Division to provide a comprehensive solution for Rule 21 that addresses the data collection, protocol and security at the Edge as well as data collection and integration at the Utility or Aggregator level as well.

  • Edge Software that supports Modbus, DNP3, IEC 61850, DLMS and IEEE 2030.5 with X.509 support and Cyber security support
  • Edge Hardware that supports Modbus, DNP3, IEC 61850, DLMS and IEEE 2030.5 with X.509 support and cyber security support. The hardware also comes with Digital I/O and Analog I/O to monitor hardwired inputs or take control action.
  • Aggregator Software that support IEEE 2030.5 Server and Client, in addition to DNP3, SunSpec Modbus, IEC 61850, DLMS etc., that can  integrate with the renewable generators, batteries etc., as well as Utility SCADA Systems over IEEE 2030.5 or other Utility SCADA Protocols
  • Remote device management with monitoring & control dashboards for managing and maintaining the renewable generators and storage.

Edge Gateway Software SyncConnect have ready made templates to connect with standard inverters available in market and also support for standard protocols such as IEEE2030.5, SunSpec Modbus, DNP3 and IEC61850-90-7 which helps user to integrate any inverters, string combiners, weather sensors, battery controllers or meters seamlessly. It also supports commonly used utility protocols like IEC-60870, DNP3.0, DLMS-COSEM to connect with grid operator. SyncConnect enables secure connectivity with each device remotely for configuration and maintenance purpose. SyncConnect runs in any standard Linux OS based hardware/ Virtual Machines/ Containers.

Rule 21 Edge Software can be deployed within an Inverter, in a Controller or as a standalone gateway using any off-the shelf hardware. With support for X.509 certificate, strong NERC/CIP compliance configuration support, support for TPM and TLS 1.2 this is ideal for faster go to market. Given the support for IEEE 1547, IEEE 2030.5 and IEC protocols and security requirements together with integration capability with multiple devices, SyncConnect is ideal for building a single unit that can be deployed not just for the Rule 21 market but world-wide.

 

Rule 21 Edge Controller SYNC2101 is a compact, rugged and secure hardware that supports Rule 21 protocols like SunSpec Modbus, IEEE 2030.5 and DNP3.  It supports native Digital I/O and Analog Inputs with a comprehensive Logic Programming Engine based on IEC 61131. The SYNC 2101 controller can be used to communicate directly with Utility SCADA or head-end over IEEE 2030.5 or over DNP3 both for monitoring and also to do control action.

SYNC2101 also support protocols like DLMS, DNP3 or Modbus to interact with meters, string main units as well as other devices and sensors in the plant.

SYNC2101 supports X.509 certificate and TLS1.2 and can be configured to be compliant with NERC/CIP.

Kalki.io

Rule 21 Aggregator software based on kalki.io is a scalable SaaS / Cloud solution that supports IEEE 2030.5 Server and Client as well as OpenADR. Further it supports SCADA / Utility protocols like DNP3, ICCP and OPC UA and REST/JSON API’s.  The Aggregator will act as a Cloud Gateway for IEEE 2030.5 or DNP3 or Modbus devices enabling many to many protocol conversion and data aggregation. Depending on the agreement between the Utility and Aggregator or the Renewable Developer the Aggregator software can be configured to the appropriate protocol or interface.

With strong PKI and X.509 infrastructure in kalki.io aggregator platform customers can install and integrate their own specific PKI system to kalki.io. Support for SunSpect mandated PKI system is easily possible.

Aggregator provides remote monitoring and management of solar generation plants and its associated components by securely connecting with inverters, weather stations, irradiance sensors, revenue meters and batteries as required for the deployment.

Rule 21 implementation will result in a large number of small solar generators getting connected to the Utility Grid and communicating to the utility directly or through an Integrator. It is humanly impossible to manage, maintain and keep up to date these systems. Further cyber security audit and analysis of these systems also need to be done routinely.

Our Device Access Pack provides remote configuration and management access for field devices by securely extending the connectivity between device’s programming port and engineering tool over a public/private network. Device Access pack also can be used to acquire data from a device over a wide number of utility, industry and IOT protocols supported.
