“…Similarly, the actions to promote CPS1 compliance would not go against the BAAL Standard requirement. Figure 3 shows the cooperation between the proposed "TM-GR" logic and the existing CPS1 control logic mentioned in [66]. From the perspective of operation security, short-term security is the precondition for maintaining long-term frequency quality.…”

“…Though CPS1 concerns the frequency performance over one year, the usual control logic used is the two-layer control scheme. The bottom layer is the main control, called the Real-time Control, and the top layer is the feedback control, called the Long-Term Control [66,67]. In the bottom layer, the time unit for observation is one minute.…”

“…The test results contain wind power utilization, frequency performance, ACE performance, and the occurrences of over-limit frequency and ACE. In the CPS logic, the CPS1&CPS2 two-layer control logic is used [66]. In the Standard BAL-001-2 logic, the proposed TM-GR logic is cooperated with the CPS1 two-layer logic.…”

“…Not every case will lead to the consecutive over-limit frequency, because the total ACE size may not be large enough. The CPS2 logic ignores the correlations between ACEs [10,66], so it cannot avoid the case that the two ACEs exceed their limits simultaneously. What is more, the CPS2 logic is not designed to monitor ACE fluctuation all the time.…”

Nowadays, the Balancing Authority Area Control Error (ACE) Limit (BAAL) Standard has been adopted to replace the Control Performance Standard 2 (CPS2) in the North American power grid. According to the new standard's mechanism, a new control logic, named "Triggered Monitoring and Graded Regulation" (TM-GR) is proposed. Its purpose is to improve wind power utilization, with good BAAL Standard compliance for load frequency control (LFC). With the TM logic, according to the real-time regulating ability of areas and forecasting results of wind power output, the triggering moments to give orders are found and a defined monitoring interval is set to track the succeeding fluctuation of Area Control Error (ACE). With the GR logic, based on whether or not over-limit frequency and over-limit ACE occur simultaneously, unit output is regulated in different grades. In cooperation with the existing control logic of Control Performance Standard 1 (CPS1), the proposed logic has a higher priority. From the test results, with the proposed control logic, the utilization of wind power output increases and, meanwhile, the area's control performance meets the Standard BAL-001-2 requirements. The standard deviation of the frequency deviation is less than the target value, and the duration of over-limit ACE and over-limit frequency can both be restricted to be less than 30 min.
