Performance Enhancement of PMSG Based Wind Energy Conversion System: Experimental Analysis

Wind energy is a hopeful renewable energy which is used to generate electricity. The kinetic energy present in the wind is converted into electrical energy by the principle of Wind Energy Conversion System. This effort approaches the performance enhancement by re-design, re-fabrication, and re-implementation of Permanent Magnet Synchronous Generator-based wind energy conversion system and data logging system. PMSG connected to the wind turbine converts wind power into electricity. The proposed hardware design of PMSG aims to achieve the overall improved efficiency of the wind turbine by 7-10% of the existing hardware design. In the proposed design of PMSG overall efficiency was improved by increasing the magnet grade, reducing the air gap, and changing the winding type. A web dependent supervising system has been recognized. A data logging system was used for collection of data on wind speed, generating power, and other related data. Besides, the stored data can be observed through the website depend on data showed by the Global System for Mobile Communications. So, the user can monitor related data through the website. The Load Management System was used to balance the supply of electricity

Adaptive droop control for balancing SOC of distributed batteries in DC microgrids

To guarantee efficient and stable operation of a microgrid, overcharging and unbalanced state of charge (SOC) of batteries have to be mitigated. An adaptive droop control scheme is proposed in this study to provide energy management between distributed batteries having unbalanced SOC and different capacities. The proposed approach suggests using a droop factor proportional to the n th order of SOC in the charging mode and inversely proportional to the n th order of SOC in the discharging mode. Moreover, a modification is proposed to adapt the performance taking into account the battery relative capacity. The relative capacity of an individual battery is defined as the ratio between the maximum capacity of all batteries and the battery capacity. The proposed adaptive droop control scheme is investigated and analysed based on an accurate model of dc microgrid incorporating lithium-ion battery, photovoltaic, permanent-magnet synchronous generator-based wind energy system and constant power loads. Several operating conditions were considered to validate the proposed control approach. The proposed control scheme has been succeeded in keeping the dc bus voltage within limits and equalising SOC of batteries, either having similar or having different capacities.
