Issue with HDVC AC computation when output terminal is disconnected

Open vidaldid-rte opened this issue 1 year ago • 3 comments

Describe the current behavior

The Pull Request https://github.com/powsybl/powsybl-open-loadflow/pull/957 contains a minimal test that reproduces the issue (ACHvdcTest)

Basically when a line is disconnected from the output terminal of an HVDC station, the HVDC still delivers atcive power to that dandling terminal (and consumes it from upward).

Expected result; No electricity flow to the dandling terminal (no current, no active power, no reactive power).

Fixed for VSC HVDC during security analysis and sensi analysis by https://github.com/powsybl/powsybl-open-loadflow/pull/961

Proposal for HVDC in N_situation (disconnect in the IIDM network) in https://github.com/powsybl/powsybl-open-loadflow/pull/965

Still missing: Lccs after contingency or remedial action management.
