Test Specification TC8.TS02

Test Rationale

The test is to evaluate the performance of the MAS-based distributed voltage control scheme to maintain the grid voltage within the permissible ranges imposed by the grid regulations under different operating conditions such as high PV production with light loading, low PV production with heavy loading.

Specific Test System

Target measures

• Voltage deviation
• PV curtailment
• Load curtailment
• Losses

Input and output parameters

Input parameters

• Grid frequency
• Grid voltage
• PV penetration level
• Solar irradiance
• Load consumption Output parameters
• Grid voltage deviation
• PV inverter AC terminal current and voltage (to derive PV active and reactive power outputs)

Test Design

• First, the distributed voltage control algorithm (FuT) is deactivated. PV production and load consumption are varied in order to create unacceptable voltage deviation scenarios. The patterns of PV production, load consumption and grid voltage are recorded.
• Then, the FuT is activated. Repeat the variation of PV production and load consumption according to those patterns recorded in the first step in order to evaluate the performance of the FuT.

Initial system state

• The percentage of PV penetration is 20%
• The nominal grid voltage is 400 V
• The nominal grid frequency is 50 Hz
• PV systems are operating at most at 50% of their inverter rated powers
• Load consumption is at 50% of the peak value
• Communication between agents is established

Evolution of system state and test signals

Vary the load consumption and PV production according to the daily load curves and solar irradiance. In particular:

• Load curves: for different types of days, for instance:
  • Working days
  • Weekends
  • Holidays
  • Summer and winter days
• PV penetration ratios
  • From 20% to 100%
