Optimization methods in water system operation

AbstractOperational water management is a critical global challenge, and decision making can be improved by using mathematical optimization. This paper provides an overview of optimization techniques, both exact and heuristic, used in water management. It focuses on the use of optimization techniques in the short term: operational planning in reservoir management, control of open channels, hydropower scheduling, and operation of polder drainage pumps. Principles of model predictive control, methods for optimization under forecast uncertainty, and approaches for conflict resolution are explained with the help of educational examples and practical cases. Challenges and research questions to be addressed in the future are presented as an outlook.This article is categorized under: Engineering Water > Methods Science of Water > Water and Environmental Change Water and Life > Conservation, Management, and Awareness

A Comprehensive Overview on PV based Hybrid Energy systems

The need for usage of renewable energy resources is gaining significance due to the depleting fossil fuels and its effect on climate change. Photovoltaic (PV) based power generation is gathering momentum due to the decrease in its cost of components. However solar energy is diurnal and highly uncertain which makes inclusion of storage element indispensable. This will enhance the cost of PV based energy systems. A grid tied PV energy system with proper backup will be a more economical alternative. This paper aims in reviewing the various objectives in designing such a PV based hybrid system to make it convenient and economical. An overview of optimization techniques, energy management methodologies and modeling of PV based hybrid energy systems has been presented. The research challenges in these areas have also been included
