Active power control in PV systems using a curve fitting algorithm based on the single-diode model
Active power control in PV systems using a curve fitting algorithm based on the single-diode model
In order for a PV system to offer ancillary services to the grid, it should be capable of maintaining active power reserves and controlling its output power. In this paper, such a power regulation technique is proposed, which is based on an improved algorithm to estimate the maximum available power when operating suboptimally. The method introduced employs the fundamental equation of the single-diode PV model and applies linear least squares curve fitting to provide the model parameters in an analytical and computationally efficient way. The effectiveness of the control strategy is validated through simulations in MATLAB/Simulink, recording the system’s response inirradiance/temperature variations and reserve command step changes, in both noiseless and noisy environment. Results show excellent dynamic response and increased accuracy and reliability compared to previous approaches.

Abstract
In order for a PV system to offer ancillary services to the grid, it should be capable of maintaining active power reserves and controlling its output power. In this paper, such a power regulation technique is proposed, which is based on an improved algorithm to estimate the maximum available power when operating suboptimally. The method introduced employs the fundamental equation of the single-diode PV model and applies linear least squares curve fitting to provide the model parameters in an analytical and computationally efficient way. The effectiveness of the control strategy is validated through simulations in MATLAB/Simulink, recording the system’s response inirradiance/temperature variations and reserve command step changes, in both noiseless and noisy environment. Results show excellent dynamic response and increased accuracy and reliability compared to previous approaches.
