Student psychology and social group optimizations based modified synchronous reference frame control topology for PV-DSTATCOM

Abstract

This paper proposes the design of a modified synchronous reference frame (SRF) (MSRF) technique while incorporating student psychology based optimization (SPBO) and social group optimization (SGO) algorithms for solar photovoltaic (PV) and battery embedded distribution static compensator (DSTATCOM) for three-phase grid-tied system. For maximum power point tracking, the SPBO is used. The proposed MSRF controller provides satisfactory performance under different real-time cases. In case of night condition, the dc bus voltage is slightly reduced. MSRF may provide system stability under different faults. Due to the use of MSRF controller, the total harmonic distortion (THD) of grid current is 1.30% and the THD value is reduced by 9.72%, 23.98%, 26.14%, 66.23%, 36.59%, 38.97%, 56.38%, 30.85%, 41.44%, 75.05%, 77%, and 95.29%, respectively, as compared to the other techniques surfaced in the recent state-of-the-art literature such as (a) IT-2 fuzzy logic control (FLC), (b) type-I FLC, (c) PI control, (d) sliding mode control (SMC), (e) fuzzy and SMC, (f) indirect current control (ICC), (g) modified ICC, (h) SRF with teaching learning based optimization and SGO combination, (i) SRF with firefly and SGO combination, (j) SRF with particle swarm optimization and SGO combination, and (k) SRF control and without DSTATCOM.
