As of HYPERSIM 2022.2, single phase and unbalanced Load Flow is not Supported. This is the main reason why the DERs are not accounted in the Load Flow solution. Indeed, some blocks in the libraries below and custom blocks in general do not support the Load Flow algorithm. As of HS 2022.2, the Nominal Voltage parameter in most of the blocks mentioned above is locked: SolutionUse the Load Flow Equivalent block at the bus where the unsupported block is connected. As indicated in the OPAL-RT Wiki: In the Load Flow block Equivalent block, you will need to know the total equivalent impedance of your DER(s) at the Bus. Once you the Load Flow is executed, it will initialize the currents in all the components of you network, then the simulation will be ready to run. |
