symbolic dynamic models for highly varying power system loads

CHAPTER 3
SYNTHETIC TESTS AND RESULTS
3.1 Introduction
To check the accuracy of the proposed Symbolic Dynamic load model, various
synthetic tests were performed and on the basis of the results of these tests the model was
modified and some important conclusions were made. It may be better to check a
proposed model or hypothesis by implementing it on a synthetic set of input data. The
advantage of doing so is that the result obtained can be compared with the expected result
and the model can be modified in the first stage itself before implementing the actual test
conditions.
Appendix A contains the Matlab code for all synthetic tests.
3.2 Nomenclature
Synthetic tests discussed in this chapter can be divided into five broad categories,
depending on the different models / hypothesis to be checked:
A. Selection of the most suitable index for comparing two signals.
B. Justification of the selected index.
C. Forecasting a signal using Model 1 (single symbol checking).
D. Forecasting a signal using Model 2 (multiple symbol checking) with
Case1 (load modeling application).
E. Forecasting a signal using Model 2 (multiple symbol checking) with Case
2 (power conditioning application).
