1.05 DESIGN PROCEDURE AND REQUIREMENTS
A. The Microgrid Controller shall support the following Grid Connected functions:
1. Off Grid Preparation - Off Grid Preparation prepares the system to transition to Island mode due to an impending grid outage. Off Grid Preparation is triggered with either advanced notice of an announced rolling blackout, announced Public Safety Power Shutoff (PSPS), weather forecasts looking at high wind speeds, and encroaching major storms.
When the event is detected, the Microgrid Controller evaluates the energy required for the standby loads and prepares the energy assets (including the Generator) for the loss of the grid power.
B. The Microgrid Controller shall support the following islanded functions:
1. Islanding and Generator Control – When electricity from the grid is not available, the Microgrid Controller communicates to the relays to open the motor-operated main breaker to the facility. The microgrid controller opens the motor-operated circuit breakers connected to the PV. The Microgrid Controller dispatches the Generator and closes the motor -operated Generator breaker. Once the grid is back in service, the Microgrid Controller synchronizes the genset to the grid, communicates to the relays to open the Generator Breaker and close the main breaker to the facility.
Prior to Microgrid Controller procurement: Verify Microgrid Controller is compatible with and can interface with Generator controller.
2. Future Resiliency Function – The Microgrid Controller shall accommodate the addition of a future BESS system. When electricity from the grid is not available, the Microgrid Controller communicates to the relays to open the main breaker to the facility, and transition the BESS to grid-forming mode.
Once the internal grid is established and stable, the primary functions are related to maintaining stability of the islanded electrical network, managing the balance between generation supply (Solar PV, generator , and BESS) and load demand, and to maintain electrical safety and protection of the standby loads. When the solar PV system is generating energy, it should serve the designated standby loads and charge the BESS with any energy not required by standby loads. If there is solar PV energy not required by the standby loads and the BESS is approaching 100% State of Charge (SOC), the BESS/Microgrid Controller should begin to curtail or shut down the PV system. The BESS/Microgrid Controller should restore the PV City of Camarillo MICROGRID CONTROLLER
CH-5067-2 263713-5
system to and operational mode if the BESS can be charged and the solar PV system can operate. If the BESS reaches a low state of charge threshold and the PV system is not capable of replenishing the BESS the genset should be dispatched to supply standby loads and charge the BESS. Once the grid is back in service, the controls synchronize the inverters to the grid, communicate to the relays to close the main breaker to the facility or PV & BESS point of common coupling and transition the BESS back to grid-following mode.

REQUIREMENTS
FOR A
STORMWATER POLLUTION CONTROL PLAN
Prior to the issuance of any construction/grading permit and/or the commencement of any clearing, grading or excavation, contractors of projects with construction activities shall prepare and submit a Stormwater Pollution Control Plan (SWPCP), on the form provided herein, for the review and approval of the City Engineer and the Stormwater Program Manager.
The purpose of the SWPCP is to identify potential pollutant sources that may affect the quality of discharges and to design the use and placement of Best Management Practices (BMPs) to effectively prohibit the entry of pollutants from the construction site into the storm drain system during construction. Erosion and sediment source control BMPs should be considered for both active and inactive (previously disturbed) construction areas. BMPs for wind erosion and dust control are also included. The SWPCP may require modification as the project progresses and as conditions warrant.
The SWPCP shall be developed and implemented in accordance with the Waste Discharge Requirements and National Pollutant Discharge Elimination System (NPDES) Permit for Municipal Separate Storm Sewer System (MS4) Discharges within the Coastal Watersheds of Los Angeles and Ventura Counties, Permit No. CAS004004, Board Order R4-2021-0105, and any other requirements established by the City of Camarillo.
The applicant/owner is responsible for ensuring that all project contractors and subcontractors implement all applicable BMPs.
