Design challenges and strategic approaches in VPP development
In the design of the Wattsmart VPP program for Sonnen, Gaurav played a crucial role, facing the significant challenge of creating a system inclusive of non-Sonnen customers. To address this, he leveraged his expertise to propose an innovative, standardized approach that could accommodate a broader participant base. “A key challenge was to develop a standardized approach that would encourage participation from non-Sonnen customers as well,” Gaurav explains. His solution was to adopt a widely recognized standard that would facilitate easier participation across different manufacturers.
Gaurav’s strategic proposal involved utilizing the IEEE 2030.5 standard, which he tailored to meet specific utility requirements without overwhelming new users with the full complexities of the protocol. “I proposed a solution based on IEEE 2030.5 standard and highlighted a subset of the available features tailored to utility requirements instead of a full-blown protocol so adoption can be quick and easy,” he elaborates. This approach not only simplified the integration process but also accelerated the adoption rate, ensuring the success of the VPP program and broadening its impact across a diverse customer base.
Integration of DER
Integrating DERs into the VPP program required innovative strategies that balanced inclusivity and intellectual property protection. Gaurav recognized that relying solely on Sonnen systems would not suffice to meet the utility’s needs. “We adopted a strategy where we can make the program available for a variety of users,” he explains, emphasizing the necessity to collaborate with competitors while safeguarding Sonnen’s intellectual property. The main strategy was to implement a standard-based approach, ensuring broad participation without compromising proprietary technologies.
To achieve this, Gaurav leveraged California’s regulatory framework, specifically CA Rule 21, which mandates compliance with the IEEE 2030.5 standard. “We took the strategic decision to use this protocol and then came with a subset of controls and settings required for the program,” Gaurav notes. This decision facilitated a smooth integration process, enabling diverse systems to participate in the VPP program. The result was a significant reduction in time to market and engineering efforts, enhancing the scalability and efficiency of the system. By adopting a widely accepted standard, Gaurav ensured that the VPP program could quickly and effectively expand its user base, demonstrating the power of strategic standardization in energy resource integration.
Ensuring regulatory compliance in VPP design
Ensuring regulatory compliance was a cornerstone of Gaurav’s approach to integrating DERs with the grid. He emphasizes the critical nature of this aspect, stating, “Compliance is the most important part to ensure smooth operations along with reliability and safety.” To meet these stringent requirements, Gaurav designed inverters that adhered to key safety standards such as UL 1998, UL 1741SA, and UL 1741SB. These standards are essential for guaranteeing the safe and reliable operation of energy systems within the grid.
A pivotal element of meeting the UL 1741SB standard was ensuring interoperability. Gaurav explains, “UL 1741SB also requires systems to have interoperability capabilities, meaning systems need to have at least one communication protocol implemented out of DNP3, SunSpec Modbus, and IEEE 2030.5.” By choosing to implement the IEEE 2030.5 standard, Gaurav not only ensured compliance with UL 1741SB but also facilitated smoother integration with various grid systems. This strategic decision allowed the VPP program to operate efficiently and reliably, highlighting Gaurav’s expertise in navigating complex regulatory landscapes while advancing technological integration.
Collaborative efforts with utility companies
Collaborating with utility companies is crucial for the success of a VPP program, and while Gaurav primarily operates behind the scenes in engineering, his contributions are indispensable. He explains, “I work in engineering, so I don’t have a customer-facing role, but our sales team is always at the forefront.” The sales team plays a pivotal role in gathering requirements from utility partners, which they then relay to the engineering team.
Gaurav’s technical expertise is critical in translating these requirements into viable solutions. “They came with requirements from the utility side, and I was then able to provide my expertise for the solution,” he elaborates. This collaboration between the sales and engineering teams ensures that the solutions developed are both technically sound and aligned with the utility companies’ needs. By leveraging his technical knowledge to support the sales team’s efforts, Gaurav helps build strong, trust-based relationships with utility partners, ensuring the successful implementation and adoption of the VPP program.
Software architecture for scalable and reliable VPP systems
Gaurav had to carefully balance the needs of both customers and utility companies in developing the software solutions for the VPP program. A critical aspect of the software architecture was the integration of the IEEE 2030.5 client with the energy management system. Gaurav explains, “One needs to find a fine balance between customer requirements and utility requirements.” This meant designing a system that did not grant utilities full remote control over customer batteries, ensuring that customers still had access to their energy when needed.
To achieve this, Gaurav emphasized the importance of maintaining a buffer for customers during emergencies while still providing power for utility services. “It was very important to make sure that we always have some buffer available for the customer in the event of an emergency and still allow power for utility service,” he notes. This thoughtful approach ensured the system’s reliability and scalability, balancing the dual demands of providing consistent utility support and safeguarding customer energy needs. The result was a robust software architecture that could efficiently manage distributed energy resources while maintaining trust and satisfaction among all stakeholders.
Creative solutions that shaped success
In driving innovation for the VPP program, Gaurav explains, “I brought innovation and creativity by leveraging existing solutions which are widely available and adopted.” He believes that true innovation should be simple and easy to implement, a philosophy that guided his approach to the VPP program’s design and implementation.
A prime example of Gaurav’s innovative approach was the use of the IEEE 2030.5 protocol, which was already widely accepted in California. “We decided to use that, but we innovated a custom solution based on utility needs rather than blindly implementing the standard,” he notes. By identifying and tailoring only the necessary aspects of the standard to fit the specific requirements of the utility, Gaurav was able to create a more efficient and effective solution. This method not only streamlined the implementation process but also ensured that the system was precisely aligned with the utility’s needs, demonstrating how thoughtful adaptation and customization can drive successful innovation.
Future prospects and innovations for VPP
The Wattsmart VPP program has had a transformative effect on the broader energy ecosystem by establishing a collaborative energy model.
