Journal ArticleDOI
Energy storage for mitigating the variability of renewable electricity sources: An updated review
TL;DR: In this paper, the authors present an up-to-date review of the state of technology, installations and some challenges of electrical energy storage (EES) systems, focusing on the applicability, advantages and disadvantages of various EES technologies for large-scale VRES integration.
Journal ArticleDOI
Cumulant-based probabilistic optimal power flow (P-OPF) with Gaussian and gamma distributions
TL;DR: In this paper, the inverse of the Hessian used in the logarithmic barrier interior point can be used as a linear mapping for unknown system variables, and results using the proposed cumulant method are compared against results from Monte Carlo simulations (MCSs) based on a small test system.
Journal ArticleDOI
Operation Scheduling of Battery Storage Systems in Joint Energy and Ancillary Services Markets
TL;DR: In this article, a risk-based approach for evaluating the participation strategy of a battery storage system in multiple markets is presented, where the uncertainties considered include predicted market prices as well as energy deployment in spinning reserve and regulation markets.
Journal ArticleDOI
Probabilistic Power Flow by Monte Carlo Simulation With Latin Supercube Sampling
TL;DR: A Latin supercube sampling (LSS) combined with Monte Carlo simulation is presented to efficiently sample random variables in the probabilistic power flow (PPF) problem.
Journal ArticleDOI
Multiobjective optimal power flows to evaluate voltage security costs in power networks
TL;DR: In this paper, new optimal power flow (OPF) techniques are proposed based on multiobjective methodologies to optimize active and reactive power dispatch while maximizing voltage security in power systems.
