Power system analysis software. e.g. DINIS, IPSA, PSS/E, and DIgSILENT provide the platform upon which detailed power system studies can be conducted, encompassing steady-state, dynamic, harmonic, and EMT studies. Load flow, reactive power capability, contingency analysis, fault level, P28, harmonic analysis, transient stability, and fault ride-through are among the most common studies carried out for network planning and generation connections.
Within the LDC distribution networks, the study of reverse power flows has become a major concern in respect of voltage management and protection stability and coordination. Outputs from many of these studies can be used as evidence of Grid/Distribution Code compliance, provided the input data and/or assumptions are sufficiently accurate.
