Past, present, and potential future California adoption methodologies for renewable energy resources
Past, present, and potential future California adoption methodologies for renewable energy resources by Chase Sun
The challenge: How to streamline the interconnection of renewable generators without impacting the safety and reliability of the existing power system? Please note that the interconnection and operation of any generator, including intermittent renewable resources, will affect the power flow (steady state and fault current) and associated voltages on the existing power system. The federal and state energy policies since 1980 seeked to minimize the generator interconnection time and costs. Unstated in the policies is that the existing system and public safety are not compromised.
This presentation will attempt to answer the following questions:
- How to keep the power flow (load and fault) after each DER interconnection within the equipment ratings and the operating voltages within allowed service voltage ranges on the entire feeder ?
- How to interconnect smaller generators at low penetration levels to the existing distribution system safely with minimal studies/time/costs at low penetration levels?
- How to ensure that the future power system will stay reliable with high levels of uncontrolled intermittent renewable energy resources?
- How to transition from large central station power plants to distributed renewable power at minimal costs to the ratepayers/taxpayers ?

Past, present, and potential future California adoption methodologies for renewable energy resources
Biography:
Mr. Chase Sun is an electrical engineer with over 40 years of experience in the electric power industry. Before he retired from PG&E in 2019, he represented PG&E, on various IEEE-1547, UL-1741, California Rule 21, CEC/CPUC Smart Inverter working groups. He also provided technical support for multiple microgrid projects within PG&E.
He joined PG&E in 1977 and worked in different power system areas including, distribution, transmission, substations, and generation. He also worked in functional areas including engineering, planning, maintenance, construction, protection, project management, and asset management. He coordinated the first complete set of PG&E generator interconnection requirements in 1984. In the 1980’s he participated in multiple alternative/renewable generation projects, including the 2.5 MW Solano Wind Turbine project, and the 125 kW Moss Landing Expansion Turbine project. He also prepared a balance of plant study for a modular 1.2 MW PV plant in 1982. In the 1990’s, he led the distribution protection group within Substation Asset Management and help developed the PG&E Interconnection Handbook in 1997, as well as distribution protection requirements/standards for many distribution substation upgrade/modernization projects.
He was a key contributor on the IEEE-929, IEEE-1547, and CA Rule 21 working groups where the certification concept and the Fast Track review/approval process for the small PV inverters at low penetration levels were developed about 20 years ago. With the certification concept and the streamlined approach contained in CA Rule 21, the interconnection times for the small PV installations were dramatically reduced and the PV adoption rate increased significantly.
He received a B. S. in Electrical Engineering and Computer Science, Power Option, from UC Berkeley. He is a licensed Electrical Engineer in California, since 1981. He is also a life member of IEEE.
