This paper proposes a real time symmetrical coordinate transformation applied for the fault-ride-through when the imbalanced fault occurs in the utility power system. The power conditioner of the photovoltaic system in Japan is required to remain connected when the utility power system fault occurs under certain condition. The most popular fault is 1 line-to-ground fault. This fault causes the imbalance voltages and currents in the utility system. To have better fault ride through ability, it is indispensable quick and precise detection of the imbalanced voltages and phases. This paper presents the novel fault-ride-through control using the real time symmetrical coordinate transform from the memorized 3-phase voltage data. Simulation results show the effectiveness of the proposed method when the dc side voltage is constant and the 1 Line-Low Voltage fault. Simulation results certify that the proper change of the controller of the dc-dc converter from the MPPT control to the constant dc voltage control can perform the good FRT operation. Extended discussion about the role of the dc energy storage and the dc circuit breaker for the future dc system is also shown.

Energy storage system (ESS) has recently been highlighted because of their many benefits such as high operation reliability, fast and accurate response ability, environmentally friendly, and so on. In power system applications, ESS can play a role in either energy management or power quality enhancement. Among the ancillary services provided by ESS such as frequency regulation, peak regulation, reserve capacity, black start, and so on, we aim at evaluating the economic value in reserve capacity application and designing economic compensatory method to make sure of reasonable profits of ESS investors. More specifically, the costs and benefits of ESS in the distribution network are evaluated. In order to improve the income of the individual investors of ESS, the government can provide economic compensation for investors from two aspects: compensation for unit reserve capacity, and compensation for investment cost. The minimum compensation standards of the two aspects are calculated. When the ESS is dispatched by the grid company, except for the government economic compensation, the grid company should pay for the investors and the payment is determined based on the grid company's economic profits. Finally, an actual ESS in Shanghai is taken as the example to calculate the economic compensation offered by the government, and the calculative results verify the rationality of the proposed method of government economic compensation for energy storage investors.

This paper introduces a novel simplified model based on mathematical functions for modeling the steady-state and the dynamic behavior of Modular Multilevel Converter (MMC). The large number of switches in MMC creates a computational challenge for electromagnetic transient simulation programs, as it is extremely time consuming. The proposed model decreases the order of system's admittance matrix and derives an equivalent function of bridge arm based on capacitor voltage balancing strategy. Simulations are carried out which shows that both the transient and steady-state response of the simplified model well match that of the detailed one. The simplified model is validated to be effective and provides a method for analyzing high level MMC systems.

In this paper, a carrier-based modulation method with optimal zero-sequence signal injection has been devised to modulate the converter and regulate the DC-link neutral points' voltages of a four-level active neutral point clamped (ANPC) converter. With the proposed control strategy, the two neutral points' voltages can be well controlled with a back-to-back structure even under high modulation indices and high power factor conditions. Simulation of a back-to-back four-level ANPC configuration has validated the modulation and control strategy.

This paper presents a modified five-level hybrid converter which based on a T-type converter (T2C) with H-bridge (HB) cell. The considered converter, which is referred to as T2C-HB, utilizes merits of T2C converter and cascade H-bridge converter while avoids their disadvantages. It has high efficiency advantage over NPC in low voltage applications and doesn't need extra isolated power to supply HB part. A larger range of output voltage can be achieved based on sinusoidal pulse width modulation (SPWM). The conduction paths and H-bridge dc-link capacitors balance conditions are well analyzed in this paper. A proposed switching sequence is designed based on three principles of balancing capacitors voltage, no unwanted voltage jump appearing in the dead-time period and minimum switching losses. The validity of the modified converter, modulation strategy and switching sequence is verified by simulation and experiment results.

Due to the reactive power control capability of double-fed induction generator (DFIG), a coordinated control strategy based on coherence clustering is proposed for DFIG wind farms (WFs). According to the strategy, the difference and coherence of DFIGs are fully considered in the WF. Firstly, DFIGs are divided into different clusters according to coherence clustering method. Then different control strategies are adopted for different clusters. Followed that a WF stability coefficient index is proposed comprehensively considering the grid voltage stability and reactive power margin. Simulation results show that under the proposed coordinated control strategy, grid voltage can be effectively supported, and reactive power margin is relatively larger to meet further requirement of the grid.

Primary-side regulation (PSR) scheme is widely used in low cost and low power applications such as the cell phone charger or LED lighting. However, a major disadvantage of PSR is that the feedback signal in the control loop is not accurate enough. So it is hard to obtain better regulation either for the output voltage or for the output current. In this paper, a novel constant current and constant voltage regulation scheme with adaptive blanking method is proposed. It can acquire accurate detection cycle by cycle with low standby power loss. Moreover, in order to eliminate the influence of transformer leakage inductance on the control loop, related factors of primary-side control are analyzed in detail. To verify the efficiency of the proposed constant current and constant voltage (CCCV) adaptive blanking method, a dedicated primary-side controller integrated in a power integrated chip (IC) is fabricated. The experimental results demonstrated the prototype based on the proposed IC has excellent regulation performance.

In this paper a high-order sliding mode observer (SMO) for back electromotive force (EMF) in induction machine (IM) is investigated to achieve speed estimation and vector orientation. The observer is derived from the mathematical mode of IM and a non-singular terminal sliding surface is adopted. With the observed EMF used as the reference, an adaptive observer is designed and the corresponding adaption mechanism for rotor speed is figured out. Considering the phase property of the observed EMF out of the rotor flux, the orientation of vector control is obtained with the designed observer. The outstanding advantages of the strategy are consist of its good robustness to rotor resistance mismatch and inhabitation of the chattering disturbances benefiting from the non-singular terminal sliding mode design.
