In this paper, we propose a control framework for battery energy storage system (BESS) to provide simultaneously multiple services the electrical grid. The objective is maximize exploitation from these in presence of uncertainty (load, stochastic distributed generation, and grid frequency). structured two phases. period-ahead phase, solve an optimization problem that allocates power budgets different services. subsequent real-time phase set-points deployment such are calculated separately...

The manuscript describes a method to embed into battery energy storage system (BESS) control strategy the performance degradation associated with operation. In particular, proposed aims at minimizing of BESS electrochemical cells. A load leveling is described as case study and ageing effects current extraction are embedded constraints optimization problem. main contributions work, compared existing literature are: i) process formulated weighted throughput, thus taking account C-rate effect...

This paper proposes and experimentally validates a control algorithm for grid-connected battery energy storage system (BESS) to level the consumption of group prosumers dispatch their aggregated operation. The strategy is layered in two-stage procedure: day-ahead intra-day During operation, load leveled power profile determined by applying scenario-based robust optimization using historical measurements feeder consumption. In phase, operation dispatched according defined during stage, which...

The paper discusses the model identification, validation and experimental testing of current-to-voltage dynamic circuit models for a grid-connected MW-class battery. refers to an utility-scale 720 kVA/560 kWh battery energy storage system (BESS) is used in predictive control framework forecast evolution DC voltage as function current trajectory. identified using measurements from dedicated session where BESS controlled with pseudo random binary signal (PRBS) excite on broad spectrum. relies...

In this paper, the problem of dispatching operation a distribution feeder comprising set heterogeneous resources is investigated. particular, main objective to track 5-minute resolution trajectory, called dispatch plan that computed one day before beginning operation. During real-time operation, due stochasticity part in portfolio, tracking errors need be absorbed order committed plan. This achieved by modulating power consumption grid-connected battery energy storage system (BESS) and HVAC...

Traditionally, the safe operation of a battery energy storage system (BESS) is achieved by imposing conservative constraints on its DC bus current and voltage. By using computationally efficient single particle model (SPM), we propose to replace these with internal ion concentrations electrical potentials in order avoid quantities exceed hazardous limits. Indeed, in-depth knowledge BESS states provided SPM, enhances awareness control action allows for better exploitation power capabilities,...

Fast charging of lithium-ion batteries is today one the key technological challenges to wide adoption electric vehicles. In recent years several protocols have been proposed, having goal reducing time without hindering battery life. Although among these are promising, a comprehensive comparison them complicated by fact that in existing literature each has tested with different cells and specific conditions. This paper provides an overview as well experimental such on two chemistries (NMC...
