“…This issue is discussed in this paper and investigated in detail. There are broadly three types of control system and associated stability studies which have been considered in previous research that can be thought of as similar in nature to the present application: a) converters with the same type of sources such as, batteries [10]- [15], super-capacitors or fuel cells [16] - [17], b) converters with different types of sources such as, PV with battery, or wind/PV hybrid energy systems [18] - [21], c) converters with the same type of sources under different operating conditions such as PV panels under partial shading [7] - [8].…”

“…Therefore, the high frequency behaviour of the inner loop is more important than its low frequency behaviour. The inner current loop bandwidth can be derived by approximating the transfer function at the high frequency as shown in (16 (5)) which in turn decreases vdc,i * and vdc,i. This variation changes the designed closed loop bandwidth ωgc,i.…”

“…The stability margin will be different in charging mode but the shape of the frequency plots will show the similar change. The corresponding effect on the inner current loop has been investigated in two stages: a) using a fixed carrier based scheme and b) a variable carrier based scheme from (16). Fig.…”

“…Short-term ESSs such as superconducting magnetic energy storage (SMES) systems [6], electrical double-layer capacitors (EDLCs) [7], and flywheel energy storage systems (FESSs) [8][9][10] as well as long-term ESSs such as battery energy storage systems (BESSs) [11,12] are applied to microgrid control. ESSs can also be used to control the power flow at point of common coupling in the grid-connected mode as well as to regulate the frequency and voltage of a microgrid in the islanded mode.…”

Battery energy storage systems (BESSs) have been widely used for microgrid control. Generally, BESS control systems are based on proportional-integral (PI) control techniques with the outer and inner control loops based on PI regulators. Recently, model predictive control (MPC) has attracted attention for application to future energy processing and control systems because it can easily deal with multivariable cases, system constraints, and nonlinearities. This study considers the application of MPC-based BESSs to microgrid control. Two types of MPC are presented in this study: MPC based on predictive power control (PPC) and MPC based on PI control in the outer and predictive current control (PCC) in the inner control loops. In particular, the effective application of MPC for microgrids with multiple BESSs should be considered because of the differences in their control performance. In this study, microgrids with two BESSs based on two MPC techniques are considered as an example. The control performance of the MPC used for the control microgrid is compared to that of the PI control. The proposed control strategy is investigated through simulations using MATLAB/Simulink software. The simulation results show that the response time, power and voltage ripples, and frequency spectrum could be improved significantly by using MPC.

“…None of these technologies offer a clear advantage over the others. To provide the power and storage capabilities required by the microgrid, a hybrid solution is commonly adopted [2][3][4][5]. For this paper, the focus will be in ultracapacitors, but the same concepts can be applied to batteries.…”

Ultracapacitors (UCs), with their features of high power density and high current charge-discharge, have become the best choice for dynamic power compensation to improve the stability of microgrids and are increasingly being applied in microgrids. This paper presents the control of an energy storage system (ESS) based on ultracapacitors in the context of grid-connected microgrids. The ESS is composed of DC/AC and DC/DC converters tied by a dc link. An improved dynamic model for the ESS is proposed. Based on the proposed model a Proportional-Integral-Resonant (PIR) DC link voltage controller is proposed to maintain the DC link voltage through the charging-discharging control of ultracapacitors, capable of working properly under all operating conditions. An extra double frequency component is injected into the UC current by a R controller to dynamically compensate for DC instantaneous power and double frequency AC instantaneous power due to unbalanced grid conditions and disturbances. This feature maintains the DC link voltage constant under unbalanced conditions and increases the degrees of freedom of the DC/AC converter and thus facilitates the application of UCs in microgrids. Simulation and experimental results verify the effectiveness of the proposed control strategy. OPEN ACCESSEnergies 2014, 7 8096
