Abstract


Objectives: In this analysis, PV-Wind Microgrid with real time environmental conditions is compensated for harmonics and reactive power. Methods/Analysis: Microgrids suffer from many power quality problems which require harmonic and reactive power compensation being connected with different sources and loads. In this regard, initially a microgrid has been developed using the data from the weather monitoring system in BITS Pilani, Hyderabad Campus. Later compensation requirement has been identified and Series APF with its unique control is applied to provide power quality enhancement. Findings: The microgrid suitable for all practical conditions is developed to give an equivalent output of conventional 3 phase distribution system and the variations in the power flows causing power quality issues are observed when connected to dynamically varying reactive loads. By using Series APF in microgrid, these issues like voltage swells and sags are mitigated and thus the reactive power compensation is provided. The % THD of voltage harmonics in the microgrid is effectively improved using the novel control technique that has been implemented. Novelty/Improvement: Power quality improvement in microgrids using active power filter topology specifically in islanded mode, Identity Vector Template Generation Approach specifically towards harmonic compensation.
