Around the world, many countries have confirmed different targets regarding the penetration level of variable Renewable Energy Systems (vRES), such as solar photovoltaic and wind power, to be achieved in the next years. This situation together with favourable conditions for vRES projects, like the development of these technologies and descending investment costs, will probably lead vRES to play an increasing role in electrical power systems of the future.
However, integrating considerable amounts of vRES into power systems has several technical and economic hurdles. Particularly, their difficult to predict and highly fluctuating power output is challenging as it adds variability and uncertainty to the operation of power systems. In this context, energy storage systems (ESS) are widely esteemed to be a potential solution for the successful grid integration of huge shares of vRESs as they can provide flexibility to the operation. Battery storage can be accounted as a promising flexibility resource while it will postpone investment in the resource (generation, transmission, and distribution) expansion planning and will decrease system operation costs. One important benefit of battery storage is flexibility regulation, and hence, the battery storage systems provide high flexibility in the distribution operation procedure. Accordingly, proper sizing of the flexibility resource, e.g., batteries, is important for investment planning decisions and siting is key for its effective operation and for the utilization of the grid. The siting and sizing decision differs based on the flexibility services required and the type of battery storages available. These can be categorized as mobile (electric vehicles), distributed (home batteries), centralized (grid storage) and hybrid (any combination of the three others). Due to the fact that Australia is facing a big challenge, where motivated renewable energy integration targets are taking place and future massive integration of solar energy are under discussion, it is important to find a robust solution for the integration of vRES and ESS into the system.
Alireza Heidari received his M.Sc. degree in power engineering from Iran University of Science and Technology, Tehran, Iran, in 2006. Then he joined one of the newly established and fast-growing universities in Iran (University of Zabol) to start his career as an academic staff. His desire to further expand his career and research skills brought him to the University of New South Wales (UNSW) where he finished his Ph.D. in 2016. He was an active member of Australian Energy Research Institute (AERI) and involved with research and teaching duties at UNSW in different schools. Through his successful performance, he awarded the Postdoctoral Writing Fellowship at UNSW. He has a solid experience in teaching and supervision both at undergraduate and postgraduate levels, curriculum development, online course development, lecturing, tutoring and lab demonstration. Further, he has an extensive background in managing end-to-end academic research programs specifically in power systems and battery energy systems, inclusive of strategic planning, modeling and optimisation, identification of research partners and funding opportunities, and publishing in leading journals and conferences. He published over 30 manuscripts in peer-reviewed and top-ranked journals and scientific international conferences. Due to his professional engagement with academics and industries he has been promoted to be an IEEE senior member which is an honour bestowed only to those who have made significant contributions to the profession. Currently, he is working at Intelligent Energy System as a consultant and focusing on modelling and simulation of utility-scale battery energy storage systems.
