Output Control
For output control of PV power generation, application conditions vary between electric
power companies while interface methods differ between manufacturers of PCS.
CSD will consult with customers to offer an optimal choice.
Example of output control configuration

New control

Obtains output control schedule from electric power company’s server
regularly and controls output of PCS according to command value.

Functions

PV-Megane Features✓ Cloud computing service
Collects, accumulates and manages data in the cloud, eliminating the need forservers and hardware, and reducing initial cost.

✓ Achieves low cost by packaging devices and software necessary
for monitoring of solar power plant
CSD’s experience in building microgrid EMS results in a slim configuration inwhich communication control devices, I/O devices, and software are packaged.
It can be applied as a component of microgrid.

✓ Possible to configure the system with different measurement scales
It is possible to configure the system in accordance with various levels of measurement
scales from central inverter, string inverter, power collection box to string unit.

✓ Supports various types of system configuration
Flexibly supports upgrading of existing on-premise system to cloud-based systemand building of a new cloud system.
(*System configuration for on-premise system is possible.)✓ Carries out various performance diagnoses of facilities
Through real time monitoring of solar power plant and equipment
performance diagnosis of power generation performance and conversion efficiency of PCS,
it contributes to maintaining long-term feasibility of operation.

✓ Output control assistanceDescription

Monitoring of power generationand operation status

Displays the current status of power generation, including generated power and its amount,solar radiation intensity, temperature, etc.

Operation status of PCS

Displays detailed operation status of each PCS with graphs.

Trend chart display

Graph displays performance data of any power plant.

Power generation reportCreates daily, monthly, and annual reports, which include the amount of power generation,
solar radiation, and outside temperature with graphs.

Alarm history

Abnormalities detected in power plant and alarms are chronologically displayed. Detection
follows the setting of alarm filter.

Mail notification when detecting
abnormalities

When abnormalities are detected, alert notifications are sent via mail. Notification
recipients and alerts level can be configured.

String monitoring

Regularly collects and saves the data of each string. The data include voltage, current, andelectric power.

List of alarm and event

Refined search by keywords related to any event and alarm.

Form output

Daily, monthly, and annual reports as well as the list of event and alarm are displayed inprinting screen.

Export of measured data

Exports measured data to CSV file. Data include daily, monthly, and annual reports and trend.

Performance diagnosis of power
generation

Conversion efficiency of PCS, power generation efficiency, power generation performancemonitoring, capacity utilization rate, etc.

Power generation diagnosis

Comparison diagnosis between expected and actual amount of power generation per PCS or string.

(optional)

Power generation amount forecast(optional)

Obtains output control schedule from the electric power company’s server periodically andcontrols output of PCS. CSD’s expertise in building microgrid EMS and VPP ensures
minimization of power generation loss.

Output control of PV power(optional)

Forecasts the amount of power generation for a few days based on weather forecasting modeland power plant’s facility specifications.
Regularly obtains output control schedule from electric power company’s server and controls
output of PCS.

Sample Screen✓ Sends notification mail when detecting abnormalities
When detecting abnormalities, it sends an alert notification mail to minimize power generation loss.
