PROJECT TITLE :

Power Management for Improved Dispatch of Utility-Scale PV Plants

ABSTRACT:

This paper proposes a rule-based power management algorithm to enable the dispatch of a utility-scale PV power plant consisting of a hybrid energy storage system, in accordance with the Australian national electricity rules. This algorithm is purposely designed to manage the instantaneous power of a PV plant with the same level of dispatchability as standard power plants. Additionally, the proposed algorithm is robust underneath giant forecasting errors (up to sixtypercent) of solar irradiance and it will be easily implemented in follow. Specifically, this algorithm can be executed inside seconds even when considering detailed market operation and model nonlinearities. A 30 MW PV plant, as well as a seven.5 MW/one.25 MWh vanadium redox battery and a one.five MW/zero.25 MWh suppercapacitors bank, has been modeled using MATLAB/Simulink and PLECS software surroundings. The simulation results were based mostly on various situations and confirmed the effectiveness of the proposed power management algorithm. It's been shown that even in the worst-case scenario of solar forecasting error of 60percent, the proposed algorithm still managed to deliver over ninety fourpercent of the available energy for a given solar irradiance profile of one month.
