Newton Raphson, Current Iteration (Gauss Siedal), Voltage Drop (for radial networks) and Extended Newton Raphson Maximum iterations and convergence tolerance Tap settings & phase shifting will be adjusted automatically to control terminal voltage & active power at specified values Slack powers can be distributed among one or more buses Limit checks & control on generator P & Q are provided It is possible to start iterations with initial conditions apart from flat start Acceleration for Current Iteration method can defined by the user Loss sensitivities wrt bus P & Q injections are calculated to decide placement of generators & capacitors Helps to decide the loads on distribution transformers when maximum loading on the radial feeder is know Power exchange between areas/zones can controlled with/without wheeling, used in transmission network analysis Uses detailed models of HVDC & FACTS devices in load flow analysis LF calculations for unbalanced loading and asymmetrical network configurations (including HVDS) are possible Calculations for a (sub)part of the network (partial network) can be done Networks with different voltage levels and configurations (mesh, loop, radial & etc.) can be analyzed DC network along with AC-DC/HVDC(including multi terminal)/FACTS networks also can be analyzed Calculations also possible at other than nominal system frequency (50Hz) with detailed equipment frequency models and generators damping (load reduction factors) Different kind of load models (Const. Load Flow Analysis (LF) Iterative methods Iteration control Automatic transformer regulation controls Distributed slack Control over generator P & Q Flat start Controlled acceleration factor Loss sensitivity calculations Load balancing Area/Zone control Extended Newton Raphson method Asymmetrical network LF analysis Calculation for partial networks Mixed voltage levels & network configurations AC/DC/AC-DC/HVDC/FACTS networks Nominal frequencyįlexible load modelling Load scaling Domestic load models Voltage limit checks and overloading conditions
