Synthesis of system power profile and temperature sensitivity analysis

This paper is to investigate the load composition of power systems by load survey study and to perform the temperature sensitivity analysis of system power demand. The stratified random sampling has been applied to select the test customers so that the typical load patterns derived can represent the load behavior of each customer class with specified confidence level. The contribution of system power consumption by each customer class can be derived with the application of load patterns obtained and the total power consumption of all customers within the same class. To analyze the impact of temperature rise to the system power consumption, the temperature sensitivity of power consumption for each customer class has been solved. The increase of power consumption for /°C temperature rise has been determined by the load composition and temperature sensitivity.
