Photovoltage, energy storage and power distribution at business parks

Commercial & Industrial Solar + Storage

Let the light come out, save it, and use it if you need it. Move!

• Plan to implement three tiers of synergy to integrate photovoltaic, storage, park loads and grid-connected points into the movement and to improve the rate of new energy consumption and system economy while meeting the grid-connected power boundary.

Overview of real-time operations EXPORT LIMIT
Photovoltage 2.46 MW
Park load 1.82 MW
Battery charge 0.51 MW
Network power 0.13 MW
Export ceiling 0.15 MW
Battery SOC 58% Real-time status
Light
Solar co-planning Common design of capacity, power and grid-connected boundaries.
Complex
Power tracking smooth Reservoir can quickly compensate for the predictions and real-time deviations.
Afternoon
At noon, it's turning. Increase spontaneous self-use rates and reduce discard light.
Sector

DAY-AHEAD PLAN

Plan plan to optimize and save power

REAL-TIME ACTUAL

Real-time layer execution of tracking and deviation correction

SOC Upper 90%
SOC Floor 20%
Storage absorbs → Planned implementation (photo voltage/ Load) → Critical hold, plan resume.

Prognosis of decision plans, real-time control of processing deviations

With a grid site as the boundary, EMS converts weather and load uncertainty into an enforceable charge and power command.
