“…Instead, good control practice provides a timely control of generation [3] and seeks to make ACE independent of time of day by limiting its correlation with the daily load curve [1], [4]. As advocated in [1], this is the most cost-effective way to maintain proper interconnection performance.…”

“…The goal was to set each of these limits to observed values to prevent increases in ACE autocorrelation and thus coincidence. These control concepts were presented in a technical paper in 1995 [23]. The CCTF began to move forward with the implementation of the C-criteria, distributing information to the industry and scheduling a workshop to review the foundations of the criteria.…”

Frequency control is an essential requirement of reliable electric power system operations. Determination of frequency control depends on frequency measurement and the practices based on these measurements that dictate acceptable frequency management. This report chronicles the evolution of these measurements and practices. As technology progresses from analog to digital for calculation, communication, and control, the technical basis for frequency control measurement and practices to determine acceptable performance continues to improve. Before the introduction of digital computing, practices were determined largely by prior experience. In anticipation of mandatory reliability rules, practices evolved from a focus primarily on commercial and equity issues to an increased focus on reliability. This evolution is expected to continue and place increased requirements for more precise measurements and a stronger scientific basis for future frequency management practices in support of reliability.Frequency Control Performance Measurement and Requirements iii

“…There has been a tremendous growth of the HVDC transmission system due to economics of power transmission, technical performance and reliability. Hence, it has been applied widely in operating a DC link in parallel with an AC link [2][3][4][5] interconnecting control areas to get an improved system dynamic performance with greater stability margins under small disturbances in the system [6]. Only scantily information is available on LFC of interconnected power systems connected via HVDC link in parallel with ac link.…”

Abstract:A new design of decentralized Load Frequency Controller for interconnected thermal non-reheat power systems with AC-DC parallel tie-lines based on Genetic Algorithm (GA) tuned Integral and Proportional (IP) controller is proposed in this paper. A HVDC link is connected in parallel with an existing AC tie-line to stabilize the frequency oscillations of the AC tie-line system. Any optimum controller selected for load frequency control of interconnected power systems should not only stabilize the power system but also reduce the system frequency and tie line power oscillations and settling time of the output responses. In practice Load Frequency Control (LFC) systems use simple Proportional Integral (PI) or Integral (I) controller. The controller parameters are usually tuned based on classical or trial-and-error approaches. But they are incapable of obtaining good dynamic performance for various load change scenarios in multi-area power system. For this reason, in this paper GA tuned IP controller is used. A two area interconnected thermal non-reheat power system is considered to demonstrate the validity of the proposed controller. The simulation results show that the proposed controller provides better dynamic responses with minimal frequency and tie-line power deviations, quick settling time and guarantees closed-loop stability margin.
