PV Layout Optimization

The centralized photovoltaic power station layout optimization function is officially launched on Greenwich.

Product Features：

Revenue oriented optimization

  1. Initiative the method to optimize capacity ratio and tilt angle of pv array with the goal of improving the economy in the industry.

  2. Support the consideration of feed-in price, component price, rental fee and payment period in economic optimization

  3. Support selecting available array areas based on slope and hill shade on mountain projects.

  4. Support array design of matching different inverters with different components

  6. Complete the layout optimization of 100MWp pv power station within 10 minutes

Friendly interaction and convenient operation

  1. Support exporting AEP time series of pv power station .

  2. support exporting available array areas on mountain projects.

  3. Support Greenwich existing functions such as polygon, restricted area, terrain, and calculation task.

  4. Use Apollo solar resource data to calculate AEP.

  5. Support customizing flat terrain on layout optimization of plain areas.

  6. PV array overview clearly display the layout summary, annual power generation, block parameters, energy flow diagram, and section summary.

Applicability Analysis

  1. Add load AI aerodynamic calculation method in RANS calculation.
  2. Optimize the prediction model of headroom risk and improve accuracy of headroom risk.
  3. Optimize the judgment logic of risk level to reduce risk misjudgment.
  4. Optimize applicability analysis report template.

WRA

  1. Add Chinese version of WTG-GROUP uncertainty analysis with 5y uncertainty calculation result.

  2. Add wind speed information under standard conditions in WTG-GROUP calculation result. Add Summary sheet to exported excel file.

  3. The error of AI modified model is taken into account in cross check.
