limit "analysis type"

[catkins-miso]

As a Ratings Provider who might be an RC, a TO, or a TOP I want to indicate the analysis that set the rating Whenever I provide a rating for any power system resource, including transmission facilities and interfaces, So that various operations coordination activities, including transmission service request processing, can utilize only appropriate kinds of ratings/limits Without assuming that a given power system resources is always thermally- or stability-limited Nor requiring that the continuous and emergency ratings be likewise constrained.

[catkins-miso]

Idk yet which is more appropriate: Limiting-Analysis = [THERMAL, STABILITY, UNKNOWN] or Limiting-Analysis = [THERMAL, TRANSIENT, VOLTAGE, SMALLSIGNAL, UNKNOWN] or Limiting-Analysis = [THERMAL_LOADING, VOLTAGE_STABILITY, ANGULAR_STABILITY, UNKNOWN]

[catkins-miso]

Implementation sketch: Put a default Limiting-Analysis in the header and add an optional "limiting-analysis" to each rating type. Without the default-limiting-analysis, which is also optional, the clearinghouse provider is obliged to impute a value of UNKNOWN for all ratings.

{"proposal-header":
  {"default-limiting-analysis":"THERMAL"},
  // usual yadda yadda
  },
 "ratings": [
    {"periods": [
      {"continuous-operating-limit":
        {"mva":150, "limiting-analysis":"TRANSIENT"}
        // emergency limits might have a differing limiting analysis
      }
    ]}
  ]
}
