An analogue model of electrical power system bulk load, suitable for dynamic and transient stability studies has been developed. The load real and reactive power are simulated as nonlinear functions of voltage and linear functions of frequency. Reactors and capacitors for voltage control, and inertial real power are included also. Application to a simple system has shown that dynamic stability limits and critical clearing times are significantly dependent on load voltage and frequency parameters where load centers are close to power stations. The dynamic stability limit may be expressed as a quadratic function of the voltage and frequency sensitivities of the load real and reactive power.
