Power system loads have different characteristics. The large single loads are industrial in nature, such as steal and aluminium smelting plants. In the commercial sector, loads for supermarkets or railway transportation are large by nature. Residential loads are always treated in the small load category. Smaller embedded generations, such as roof top solar panels and small-scale wind turbines installed alongside households, are included in the loads as a negative contribution for steady-state analysis purposes, although this representation is a crude simplification. With more and more power electronic interfaces to the loads, the profile and characteristic of loads is evolving. The overall characteristic of loads seen by the network is further changing with the increasing penetration of electric vehicles. The size of the load and the load mix changes continuously. One of the tasks involved in power system modelling is to appropriately capture the behaviour of this mixture of loads while limiting the complexity of the modelling. This is achieved using a simplified representation of the loads in the network, where the cumulative behaviour of a segment of the low voltage part of the grid including its loads is represented by a single load at the grid supply point.
This chapter discusses various types of load models, with a detailed description of the frequently used ZIP (constant impedance/current/power) modelling. A four-machine system is used to investigate the effect of various load characteristics on the small signal behaviour of the system poles. While carrying out a dynamic simulation in Matlab/Simulink, ZIP load modelling introduces an algebraic loop in the system, and this chapter discusses two techniques for breaking the loop and compares both techniques for validation purposes.
