Abstract
This chapter presents diversified harmonics modeling for power system networks. The chapter starts with a description of a simplified steady-state stability model. Network stability is classified based on load change and disturbance. Then the presence of harmonics is introduced step by step. Then a brief discussion is presented on how the model will look in the presence of harmonics. The change of operating points due to harmonics is discussed in a case study.
Keywords: Harmonics, harmonic operating point (HOP), harmonic power, load angle, maximum power, power equation, power system, stability
2.1 Introduction
The term ‘stability’ in the power system indicates the state of ‘synchronism’ maintained during operation. Power system networks involve synchronous generators along with other types of generation units. Moreover, they feed power to a variety of loads of diverse and dynamic characteristics. Also, power system networks face different types of faults and other types of disturbances. All these make the operation in synchronism a very difficult and challenging task to be maintained. The maximum power that can be delivered to maintain stability is known as the stability limit.
