What is the significance of power system load forecasting? What are the load forecasting methods?

1, narrow sense load forecasting (load under normal operation) is the premise of making power generation plan;

2. Generalized load forecasting (load under the influence of extreme meteorological disasters) is an essential link of power grid security early warning;

3. There are many methods of load forecasting, which are not easy to be summarized. There are mainly the following types, mainly for load forecasting in a narrow sense:

1) time series method;

2) Similar day method;

3) fitting method of meteorological factors;

4) Sequence analysis.

There are also some methods to predict load interval and reliability.
