Lithium-ion battery energy storage systems (BESS)with their present state of technology and economic maturity possess huge potential for catering short-term flexibility requirements in smart grid environment. However, it is essential to model in detail the complexity of non-linear battery system characteristics and control of their adjoining power electronic interfaces. More detailed and accurate modelling of components, enables improved overall power system optimization studies by considering both, component and system level aspects simultaneously. Therefore, this paper develops an equivalent circuit model (ECM) for Lithium-ion battery and Lithium-ion nickel-manganese-cobalt (NMC) battery cell is modelled as a second order equivalent circuit (SOEC), including C-rate, temperature, state-of-charge and age effects. Secondly, detailed controller design methodology for DC/DC-and DC/ACconverter interfaces are developed to enable advanced grid integration studies. Overall, BESS integration design was validated by simulation studies in Simulink Simpowersystems platform.

Abstract: The utility of electric power plays a major role in economic development of a country. However, the demand for electrical energy goes on increasing every day. In order to meet out the demand for electricity, Renewable Energy Source (RES) has been identified as the alternate for electricity generation. Among the various RES, PV system has added consideration throughout the world due to its easy accessibility, boundless nature and of low maintenance cost. Since the voltage obtained from PV is not suitable for high power applications, a DC/DC step up converter is introduced. This converter should have reduced output voltage ripple which is an important factor that influences the overall performance of PV system. Hence, this work studied about the different topology of converter suitable for PV systems to have a better efficiency.

“…Due to its flexible control scheme that allows the easy inclusion of system constraints and nonlinearities of the system, MPC has raised much concern in the last few years [12,13]. In MPC, different definitions of the cost function are possible, considering different norms and including several variables and weighting factors [14][15][16]. Taking the advantages of MPC, a new PDFC strategy is developed.…”

“…However, the control objectives in this paper are the flux magnitude |ψ V | and the power angle δ p . The first term in Equation (14) reduces the flux ripples, while the second term contributes to power angle ripple reduction. For example, a larger value for k 1 implies a higher priority for the flux regulation.…”

Abstract:Voltage source inverters (VSIs) have been widely utilized in electric drives and distributed generations (DGs), where electromagnetic torque, currents and voltages are usually the control objectives. The inverter flux, defined as the integral of the inverter voltage, however, is seldom studied. Although a conventional flux control approach has been developed, it presents major drawbacks of large flux ripples, leading to distorted inverter output currents and large power ripples. This paper proposes a new control strategy of VSIs by controlling the inverter flux. To improve the system's steady-state and transient performance, a predictive control scheme is adopted. The flux amplitude and flux angle can be well regulated by choosing the optimum inverter control action according to formulated selection criteria. Hence, the inverter flux can be controlled to have a specified magnitude and a specified position relative to the grid flux with less ripples. This results in a satisfactory line current performance with a fast transient response. The proposed predictive direct flux control (PDFC) method is tested in a 3 MW high-power grid-connected VSI system in the MATLAB/Simulink environment, and the results demonstrate its effectiveness.
