2019 Expansion planning and flexibility optimization (Competition & panel)

2019 Competition & panel: Emerging heuristic optimization algorithms for expansion planning and flexibility optimization in sustainable electrical power systems

The expansion planning and flexibility optimization of sustainable electrical power systems are facing higher complexity introduced by massive integration of variable renewable generation,  the increasing need of FACTS and HVDC devices for flexibility in highly interactive energy markets, responsive demand, and multi-energy sector coupling. Therefore, the expansion and flexibility management problems involved in investments decision making and operational planning need consideration of more accurate models such as non-linear models, probabilistic models, and a large number of decision variables. This entails mathematically complex and computationally expense formulations, which cannot be tackled by classical optimization tools.

This panel will introduce a new testbed concerning with optimal transmission expansion planning. The testbed is based on three benchmark systems to evaluate the feasibility and effectiveness of optimization algorithms in systems of different characteristics and size.  Also, the panel will present the results and a statistical comparative evaluation of the performance of different emerging heuristic optimization algorithms, which are developed by different researchers worldwide. These researchers will be challenged to solve the cases of the testbed, which will be treated as black-box problems. They are only allowed to improve the methodological framework of their algorithms.
