Multi-frequency oscillation is a new type of oscillation issue in the power system caused by control interactions of renewable converters and power electronic devices. This paper investigates the impacts of cable parameters to multi-frequency oscillations of voltage source converter (VSC) connected through AC cable. The analysis is based on small-signal sequence impedance models. Due to cable capacitance, the frequency of impedance resonance of cable is much lower than that of transmission line, which raises the risks of oscillation. Also it is found that cable of lower rated voltage has higher risks of multi-frequency oscillations. The theoretical study is demonstrated by time-domain simulations based on PSCAD.
多频振荡是电力系统中由可再生变流器与电力电子器件控制相互作用引起的一种新型振荡问题。本文研究了电缆参数对通过交流电缆连接的电压源变换器多频振荡的影响。该分析基于小信号序列阻抗模型。由于电缆电容的存在,电缆的阻抗谐振频率远低于传输线,增加了振荡的风险。同时发现,额定电压越低,电缆的多频振荡风险越大。基于PSCAD的时域仿真验证了理论研究的正确性。

The active power and reactive power of modular multilevel converter based HVDC (MMC-HVDC) can be decoupled independently, and can be rapidly controlled. Based on this characteristic, a supplementary frequency-voltage controller (SFVC) is designed to improve the frequency and voltage stability of MMC-HVDC connected to the weak receiving system. A detailed electromagnetic transient model is built in PSCAD. The simulation results of different disturbance locations and time durations show that the SFVC can quickly restore the frequency and voltage stability of the receiving system. The effectiveness and superiority of the proposed SFVC are proved.

With the popularity of electric vehicles, the impact of large-scale electric vehicle access to the distribution network has become more obvious. In this context, a real-time rolling optimization scheduling strategy for charging stations that takes into account the reactive power response of electric vehicle charging piles is proposed, fully considering the space-time distribution characteristics of electric vehicles and the active and reactive interaction capabilities between charging stations and the grid. Establish a two-layer model to optimize the scheduling of the active and reactive power of the charging station in time and space. The quadratic programming and the second-order cone programming are used to solve the upper and lower models respectively. Finally, the improved IEEE33 node distribution network system is used for simulation. The simulation results show that the strategy can effectively reduce the system load peak-valley difference and reduce the system network loss, improve system voltage level, etc.

The stable operation capability of the doubly-fed induction generation (DFIG) based wind power grid-connected system will vary with the wind speed, yet the existing mathematical models of DFIG is limited to some specific wind speed points, which may not be directly applied to stability analysis in the all wind speed operating conditions. The wind speed is used to characterize the steady state operating point in this paper, while considering the single-input dual-output (SIDO) characteristics of DFIG, a two-variable admittance model are proposed. Further, the two-variable admittance model are used to analyze the stability of DFIG based grid-connected system. The simulation results indicate that the established admittance model can precisely reflect the frequency characteristics in the entire wind speed operating space, which provides basis for accurate analysis and effective improvement of the stability for new energy power generation equipment.

The DC line fault signal contains rich transient information. Aiming at the problems of poor reliability and insufficient sensitivity of single-ended protection of traditional DC transmission lines, a protection principle that uses only transient currents to achieve full-line rapid operation of DC transmission lines is proposed. The influence of the HVDC transmission line and the constructed boundary model on the fault transient signal is analyzed, and the multi-resolution wavelet is used to analyze the fault current signal and obtain the corresponding wavelet energy. The bipolar DC transmission system model based on the CIGRE model was built on PSCAD and simulated. The results show that the method can accurately determine the fault within and outside the fault zone, and is not affected by the transition resistance and line length, and has high accuracy.

In order to more profitable allocate the operations of large-scale battery storage stations (BSSs) with locational diversity across various electricity markets, a bilevel formulation is proposed to coordinate the bidding decisions of BSSs in energy, reserve and regulation markets. In which, total profit of BSSs can achieve a global optimum with the consideration of power flow constraints under locational marginal pricing (LMP) clearing schemes. Meanwhile, the battery degradation cost is molded and the stochastic extension with uncertainties are considered. Moreover, the bilevel problem can be converted to mixed-integer linear programming (MILP). Case studies validated the performance of proposed method.

Auction mechanisms have been widely applied in the electricity market for determining the market price and energy trading. Those who take demand response into consideration are promising to enable interaction of end-users with the grid. In addition, blockchain is an effective way to secure the energy trading in the electricity market. In this paper, a new pricing mechanism based on auction is proposed to induce users to participate actively with the goal of social welfare maximization and to reduce the storage burden of blockchains. In this mechanism, each user submits individual bids to the system/auctioneer. The auctioneer makes optimal allocation with respect to the submitted bidding profile and broadcasts the market price to all the participants. To obtain the optimal trading strategy, an energy distribution algorithm is proposed. In this algorithm, each individual user updates its best response with respect to the market price, which is determined by the set of previous bidding curves. The expected system price determines the user’s best response while the resulting load pattern will change this price reversely.
拍卖机制已广泛应用于电力市场,用于确定市场价格和能源交易。那些将需求响应考虑在内的人有望实现终端用户与电网的交互。此外,区块链是确保电力市场能源交易安全的有效途径。本文提出了一种新的基于拍卖的定价机制,以诱导用户积极参与,以社会福利最大化为目标,减少区块链的存储负担。在这种机制中,每个用户向系统/拍卖商提交个人出价。拍卖商根据提交的投标资料进行最优分配,并将市场价格广播给所有参与者。为了获得最优交易策略,提出了一种能量分配算法。在该算法中,每个用户根据市场价格更新自己的最佳对策,而市场价格是由之前的竞价曲线集决定的。预期的系统价格决定了用户的最佳响应,而最终的负载模式将反过来改变这个价格。

A Novel Asymmetric Duty Modulation Control of Dual-Active-Bridge for LVDC Applications LVDC双有源桥的非对称占空调制控制

As a traditional dual-active-bridge (DAB) converter control strategy, phase-shift (PS) control has some defects, including the large root-mean-square (RMS)value of current stress when the voltageson both sides mismatch. Therefore, asymmetric duty modulation (ADM) control is introduced, which can effectively reduce the (RMS) current and improve the efficiency of DAB. However, the influence of the backflow power is seldom considered in the research of ADM control. Subsequently, in this paper, compared with the conventional ADM control, a novel ADM control scheme is proposed, where the backflow power grows down substantially. In the meanwhile, there exists tremendous RMS value of current stress in DAB when operating under EPS control. Aforementioned modified ADM control can retard the RMS value of current stress gradually. Finally, the effectiveness of the proposed control scheme is verified by simulation results.
作为传统的双有源桥(DAB)变换器控制策略,相移(PS)控制存在一些缺陷,包括当两端电压不匹配时电流应力的均方根(RMS)值较大。因此,引入非对称占空调制(ADM)控制,可以有效地降低(RMS)电流,提高DAB的效率。然而,在ADM控制研究中很少考虑回流功率的影响。随后,与传统的ADM控制相比,本文提出了一种新的ADM控制方案,该方案的回流功率大大降低。同时,在EPS控制下,DAB的电流应力存在较大的均方根值。上述改良的ADM控制可以逐渐延缓当前应力的均方根值。最后,通过仿真结果验证了所提控制方案的有效性。

Therefore, asymmetric duty modulation (ADM) control is introduced, which can effectively reduce the (RMS) current and improve the efficiency of DAB. However, the influence of the backflow power is seldom considered in the research of ADM control. Subsequently, in this paper, compared with the conventional ADM control, a novel ADM control scheme is proposed, where the backflow power grows down substantially.
