Hybrid Microgrid Energy Management Using Hybrid Energy Storage System | Chapter 4 | Theory and Applications of Engineering Research Vol. 6

In this study, an energy management control strategy is designed, such that it handles transient conditions effectively, maintains the DC link voltage constant, and improves battery life by reducing the stresses placed on the batteries. Power demand all around the world is increasing day by day and conventional energy sources are getting depleted. In order to meet the power demand and to reduce the carbon emission caused by the conventional energy sources, alternate energy sources are important. Renewable energy sources are the promising solution. Wind and solar are two reliable energy sources among the various renewable energy sources. In this proposed paper Wind and PV energy-based DC microgrid is proposed with super capacitor and battery hybrid energy storage systems. Constant DC link voltage is the replication of energy balance in DC microgrid. The main goal of the proposed microgrid energy management algorithm is to maintain the constant DC link voltage irrespective of the intermittent nature of the renewable energy sources and load variations.  Energy management system is designed in such a way that transient power requirement caused by sudden load variation, generation change and due to fault condition is quickly handled by supercapacitor which is high power density device and average power requirements is handled by battery energy storage. Proposed energy management system offers fast dc link voltage and HESS is connected parallel to DC bus via bidirectional DC -DC converter, enables power flow in both the directions. Slow response of the battery is compensated using battery power compensating input to the super capacitor controller. The proposed energy management system improves battery life span along with effective DC link voltage regulation. The proposed control algorithm of energy management is compared with conventional energy management system in MATLAB/Simulink and presented for various studies.

Unconsidered Role of Electric Forces in Polar Snowair Interactions | Chapter 1 | Current Perspectives to Environment and Climate Change Vol. 4

 Processes that occur inside polar snow cover significantly affect polar atmosphere but they are still

poorly understood. Most studies consider photochemistry as the dominant mechanism of chemical
transformations but recent field data cannot be interpreted only by such photochemical model. A
concept is proposed to consider electric phenomena that are well known to physics but their role was
never analyzed by snow chemistry specialists. But there is a question on how to differentiate
influences of photo effects and electric phenomena. It can be supposed that these factors are not
independent. On the contrary, they reinforce each other and act synergistically.
