With the rapid development of distributed energy, the power grid, especially the urban power grid, is facing many challenges. In this paper, the concept of DC distribution station is proposed. As a key component of DC distribution system, DC distribution station will play the advantages of DC distribution technology to promote the transformation of traditional urban power grid into a new urban power grid. A reasonable overall topology is proposed, and the appropriate voltage control strategy is selected. Besides, the simulation model of DC distribution station is built in MATLAB/SIMULINK. The simulation under steady-state condition verifies the feasibility of the DC distribution station and the correctness of the control strategy.

风光互补发电系统利用风能与太阳能的互补特性,相比于单独的光伏发电或风力发电,其输出功率波动小。合理配置风电/光伏/储能的容量,既可提高系统供电可靠性,又可降低系统成本。针对风光蓄互补发电系统,提出一种改进的容量优化配置方法,考虑独立和并网两种模式,对风力发电、光伏发电和蓄电池的容量进行最优配置。该方法充分利用风光互补特性,在系统独立运行时,只需较小的蓄电池容量即可保证高供电可靠性,并可减少蓄电池的充放电次数和放电深度;在系统并网运行时,进一步提出采用分时段优化策略来配置所需蓄电池的容量,保证负荷供电需求和入网功率的波动特性满足要求。算例验证了所提改进优化方法的合理性和优越性。

A control scheme of electronic power transformer (EPT) in a three-phase four-wire distribution system, which included an input section, an isolating section and an output section, was researched under unbalanced loads. The simple and appropriate control scheme was developed through analyzing the system requirements of the primary side and the load requirements of the secondary side. In the input section, a dual-loop control in synchronous rotating d-q coordinates was introduced, and in the output section, a dual-loop control based on instantaneous output voltage was used. Load characteristics of EPT were investigated by using Matlab/Simulink software. Simulation results showed that, with the proposed control scheme, the EPT has good performances and the sinusoidal input current and constant output voltage can be realized under both balanced and unbalanced loads.

Loads in large scale industrial enterprises are always various and complex, causing insecure power quality. Meanwhile, some sensitive loads or precise instruments demand for high power quality. When voltage flicker or harmonics occurs, dynamic voltage restorer (DVR) can be used to stabilize the load-side voltage, which is a good manner of improving power quality. The paper explains the load demand in large scale industrial enterprises, analyzes several common voltage compensation scheme of DVR, and comes up with another voltage compensation scheme of DVR applied for double power supply with double load. A Simulink model according to the new scheme is also built in MATLAB/Simulink to test its performance. Simulation results show that the proposed scheme can guarantee the load-side voltage stability, which is an effective scheme for managing power quality.
