Update of Residential Load Profile for WECC Load Composition Model Using Cross-Correlation Method

The Western Electricity Coordinating Council (WECC) initiated development of a composite load model for transmission-level power system simulations. To more precisely utilize the model to represent the power consumption pattern for various locations of the WECC network, an up-to-date load composition dataset is required. The study in this paper updates the residential dataset of the load composition model (LCM) using latest survey or measurement data. The LCM residential dataset contains load profiles for 12 climate zones and 5 season conditions. The Northwest Energy Efficiency Alliance (NEEA) launched a study to generate the load profiles for four climate zones in the Pacific Northwest. Based on the NEEA database, a component-wise cross-correlation-based approach has been developed in this paper to reconstruct the residential load profiles of the four Pacific Northwest climate zones and to populate the new load shape data into the other eight WECC climate zones.
