The North American bulk electric system
Published in Fred I. Denny, David E. Dismukes, Power System Operations and Electricity Markets, 2017
Fred I. Denny, David E. Dismukes
From an electrical point of view, there are three systems in North America. These systems are called “interconnections.” They are: The Western Interconnection, generally including the states west of the Rocky Mountains and the Western Canadian provinces.The ERCOT Interconnection, including most of Texas. ERCOT does not have synchronous interconnections to other states and is not under the jurisdiction of the Federal Energy Regulatory Commission (FERC).The Eastern Interconnection, including the Eastern Canadian provinces and most of the United States, east of the Rocky Mountains.
Frequency and Voltage Control

The North American Electric Reliability Corporation (NERC) is the entity nowadays in charge of setting reliability standards, which include basic frequency and voltage control requirements for the interconnected North American power grid. The system under NERC’s purview, which provides approximately 4800 TWh/year of electricity to nearly 400 million people, is basically divided into eight regions, each one under the purview of a regional reliability coordinator, as shown in Figure 9.2. The figure shows that the system is divided into four asynchronous systems interconnected through High Voltage dc (HVDC) links, namely: The western interconnection, which covers most of the Western part of North America, from British Columbia and Alberta in the north to California and a small part of Baja California, Mexico, in the south, and from east of the Rocky Mountains in the east to the Pacific coast in the west.The eastern interconnection includes most of the rest of Canada and the United States, from Ontario and Quebec in the north to Florida and the Gulf of Mexico in the south, and from east of the Rocky Mountains in the west to the Atlantic coast in the east. The east and west systems are interconnected through relatively small back-to-back HVDC links.Most of Texas is served by a grid interconnected with both east and west systems through back-to-back HVDC links.The province of Quebec is connected to the rest of the eastern interconnection through major HVDC links.

A research team consisting of domain experts and analysts was involved in this case study. Frequent meetings occurred to address the problem domain. The background information presented above was shared by the domain experts. The analysts also performed the literature review that appears in the Introduction section. The broadly stated objective was to achieve WASA for the power system operated by the Western Electricity Coordinating Council (WECC). The WECC is a regional entity charged with compliance monitoring and enforcement to promote reliability in the western interconnection. The WECC is the largest such regional entity in North America that includes the provinces of Alberta and British Columbia in Canada, the northern portion of Baja California in Mexico, and all or portions of the 14 western states of the United States (see Figure 2). In order to accomplish this objective, the research team was tasked with applying DM techniques to identify and classify abnormal power system modal behaviors of the power grid for the WECC system.
