Oxford, England, United Kingdom

• Optimized energy storage sizing and placement using optimal power flow to maximize storage utilization and minimize generator costs, while accounting for storage efficiency, self-discharge, energy limits, power limits.• Benchmarked the novel optimization algorithm in terms of speed and accuracy against Gurobi mathematical optimization and meta-heuristic optimization, using techniques such as linear programming, mixed-integer quadratic programming, elitist genetic algorithm, and particle swarm algorithm.• Applied the optimization algorithms in case studies using DC OPF, AC OPF, linear storage model, and non-linear storage model to explore their effect on storage sizing and placement.• The novel method operates without requiring storage costs, which stands in contrast to other methods, where errors in storage cost estimates cause inaccuracies in sizing and placement. The methods can serve as a decision support tool, providing insights into the physical limits of energy storage amidst economic variabilities.
