Multi-purpose applications of energy storage systems in a power system network by Okafor, Chukwuemeka Emmanuel

“…A novel methodology for the optimal sizing of a BESS for the multiple functions of providing support for the frequency nadir (during contingency events), reduction of real power losses, and mitigation of voltage deviations using the deep sleep optimizer (DSO) algorithm was developed. The proposed method establishes a relationship between frequency nadir, voltage variations, power losses, and the BESS multiplier by utilizing regression analysis techniques in multi-objective mathematical formulations. …”

A 3-phase Z-source inverter driven by a novel hybrid switching algorithm by Malengret, Jean-Claude

“…A novel DSP control algorithm allows the inverter toachieve the following:· Run Space Vector Pulse Width Modulation (SV-PWM) for maximum DCbus voltage utilization while boosting the DC bus during zero space vectorstates using shoot through.· Seamless transition between modulation control and modulation / shootthrough control.· Optimised efficiency and DC bus utilisation using Hybrid Space VectorBoost Pulse Width Modulation (HSVB PWM) which is unique to thisdissertation.Such a system is particularly suited to fuel cell and particularly wind turbineapplications where the DC bus voltage is varies over a wide range resulting inthe need for a DC to DC buck/boost to regulate the DC bus to maintain a steady3-phase sinusoidal output. …”
