Investigating the Performance of Control Strategies for Voltage and Frequency Regulation in Decentralized Power Generation System
摘要
An imbalance between generation and load often occurs in decentralized power generation systems. This imbalance causes voltage and frequency deviations, which affect the stable operation of the system. This paper proposes control strategies for the system sources to regulate the voltage and frequency by balancing the active and reactive power. Various scenarios of power generation and load-demand conditions are considered to investigate the performance of the proposed control strategies. A simulation was conducted using PSCAD/EMTDC software to assess the feasibility of the proposed control strategies. Results indicate that the suggested control strategies are effective in maintaining system voltage and frequency under various operating conditions. The embedded decoupled current control approach in the proposed control strategies realizes fast compensation for transient disturbances.
