نویسندگان
چکیده
Cycle identification via the rainflow-algorithm is implemented online in a model predictive controller (MPC) for Li-ion batteries. This achieved by externalization of cycle from optimization problem. The limitation cyclic aging estimation due to short prediction horizons overcome updating and utilizing State Charge memory. Furthermore, comprehensive plant batteries presented with novel submodels calendric aging. MPC ACADO Toolkit tested aforementioned model. Simulation results indicate that—even without tuning—the clearly outperforms rule-based an extensively tuned literature.

Battery aging and the Kinetic Battery Model
Batteries are omnipresent, and with the uprise of the electrical vehicles will their use will grow even more. However, the batteries can deliver their required power for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in long lasting applications. Some detailed battery models that describe t...
متن کاملEconomic Model Predictive Control - A Review
Leveraging the advanced estimation and control algorithms for power systems have always been associated with the renewable energy sources, rational power generation, consumer stimulus, emission reduction, as well as economically viable objectives. The model predictive control (MPC) strategies, that employ an economic-related cost function for real-time control, has lately proved a numerically e...
متن کاملIterative Learning Economic Model Predictive Control
An iterative learning based economic model predictive controller (ILEMPC) is proposed for repetitive tasks in this paper. Compared with existing works, the initial feasible trajectory of the proposed ILEMPC is not restricted to be convergent to an equilibrium so it can handle various types of control objectives: stabilization, tracking a periodic trajectory and even pure economic optimization. ...
متن کاملDisturbance Handling in Economic Model Predictive Control
Economic model predictive control (EMPC) is a recent development of MPC where the usual quadratic objective is replaced by an economic objective reflecting the real cost of operation (Ellis et al., 2014). The target in EMPC is hence to directly minimize the cost of operation whereas the usual target in MPC is to keep the process close to a predetermined steady-state or trajectory (sometimes det...
متن کاملModel Predictive Control for Distributed Microgrid Battery Energy Storage Systems
This paper proposes a new convex model predictive control strategy for dynamic optimal power flow between battery energy storage systems distributed in an AC microgrid. The proposed control strategy uses a new problem formulation, based on a linear d–q reference frame voltage-current model and linearised power flow approximations. This allows the optimal power flows to be solved as a convex opt...
