Power Quality Improvement of Distribution Network Using BESS and Capacitor Bank

Abstract

The power demand around the world is increasing rapidly. The aging distribution network architectures are used by the existing utility companies to deliver power to the consumers, which significantly affects the reliability, stability and quality of the delivered power. Different techniques such as compensation devices have been used by power system engineers and researchers to maintain the quality of power transmitted to end users. In this paper, wattage and volt-amp reactive (VAR) planning scheme has been proposed by using the combination of battery energy storage systems (BESS) and compensators to deal with the vulnerability of networks to voltage drop and system inefficiency. The cost-effective combination of BESS and shunt capacitor bank will then be analyzed to indicate the benefit of the proposed scheme.

A review of battery energy storage systems for ancillary services in distribution grids: Current status, challenges and future directions

“…A BESS control for PV power intermittency smoothing using an optimized two-stage filter was proposed in Nazaripouya et al (2017). More BESS-based algorithms for power smoothing and improving power quality can be found in Lallu et al (2017); Islam et al (2020); Guo et al (2020).…”

“…Voltage sag & swell can last a long time equipment life, resulting in an "under-voltage" profile. Instantaneous, momentary, and transient voltage sags exist [9]. Voltage sag during fault condition is shown in Figure 1.…”

“…PQ enhancement is achieved using an ANN-controlled DVR [6]. To address low PQ and boost utility efficiency, electric power is analyzed [7][8][9]. Poor PQ difficulties finally lead to network economic failure.…”
