Load frequency control of two-area network using renewable energy resources and battery energy storage system

Abstract EN

In an interconnected system, the frequency and tie-line power interchange are very susceptible with the diversification of power load demand.

Literally, in a multi-area power system, the load frequency control (LFC) is substantially aimed to minimise the deviations of these parameters relatively.

Knowingly, the power production from renewable energy resources could offer promising solutions despite their intermittency (i.e.

photovoltaic/wind generation), hence in this context, a battery energy storage system (BESS) is proposed to delineate dynamic response along with grid—connection.

This study has proposed LFC with BESS control method to suppress frequency deviations for a power system and being compared with photovoltaic (PV) approach.

The effectiveness was verified using newly developed AGC30 model of Japanese Power System and was modelled using MATLAB Simulink.

Furthermore, an analysis of the tie-line power oscillations also are carried out and comparison analysis demonstrates further the reliability of the proposed model and control methods.
