RENEWABLES INTEGRATION
Coordinate grid voltage, on-site generation and site load
Solar PV changes power flow and can influence voltage at the point of connection. Voltage optimisation may complement renewable investment by addressing the voltage presented to downstream loads, but it does not create solar generation or replace inverter and network controls.
Why the interaction matters
The electrical system can operate differently during low load, high generation, export, import and battery charging or discharge. The assessment must consider each credible mode and the location of the optimiser relative to generation, metering and critical loads.
Engineering questions
Where are the point of common coupling, revenue meter, solar connection and optimiser boundary?
- Can power flow reverse through the proposed equipment?
- What voltage conditions occur during high export and low load?
- How will inverter protection and voltage response interact with the optimiser?
- Which meter boundary will separate avoided load from renewable generation?
- What happens during islanded, backup or battery-supported operation?
Financial and reporting boundaries
Assess the net value of avoided imported energy, optimiser losses, tariff effects and any operational constraints. Report renewable generation and voltage-optimisation savings as separate quantities unless the agreed method justifies another treatment.
