With the increasing penetration of distributed photovoltaic in distribution network, it is more difficult to control active distribution network (ADN). A flexible interconnection device (FID) can realize regional interconnection of the ADN through transferring power. However, the influence of installation position and number of FIDs on the ADN varies, it is necessary to analyze its operational planning model. In this study, first, a photovoltaic power and load forecasting model is established, followed by reduction of the typical scenarios. Second, the ADN operational planning model is established according to the line load balance index to analyze the coordination and determine the power transfer value of the FID in different installation positions and numbers for the ADN. Third, the net income index of the distribution network in the entire life cycle is established to analyze the economy of the ADN and determine the optimal FID installation location and quantity. Finally, numerous simulations and comparisons are carried out on the actual example system, and the results show that the FID can effectively transfer the active power, strengthen the ADN power supply level, and solve the problem of power supply imbalance caused by distributed photovoltaic access.

The manufacture of sodium sulfide through a carbon reduction process, using sodium sulfate as raw material, generatessodium sulfide by-product sediment, which has potential health and environmental impacts. Herein, a novel strategy isproposed to recover sodium oxide from the sediment by using acidic treatment and the influence of solution pH on sodiumoxide content is systematically studied. The results reveal that the sodium oxide content decreases with decreasing pH valueof the solution. At pH = 4, the as-treated sediment results in Na2O content of 3.10 wt. %, which recovery rate is about 90%. Furthermore, the influences of sintering temperature and time on compressive strength and bulk density are studied. Ingeneral, the compressive strength and bulk density increase with increasing sintering temperature and time. After sinteringat 1,300 oC for 120 min, the compressive strength and bulk density of the sintered porous ceramic are 26.66 MPa and 1.31 g/cm3, respectively. The porous ceramic, sintered at 1,300 oC, mainly consists of hauyne, gehlenite and hematite phases. Insummary, the few flaws in cell-walls result in high compressive strength of the as-prepared porous ceramics.

A T-shaped tree-like branching microchannel is designed for gas turbine blade cooling. The conjugate heat transfer characteristics of air coolant are investigated experimentally. To compare the flow and thermal performance of steam and air coolant numerically, the SSG turbulence model is adopted. The results reveal that the heat transfer coefficient is gradually increased through the whole branching microchannel. The conjugate heat transfer effects lead to a heat transfer suppression in the entrance region but an enhancement in the channel terminal region. The flow and heat transfer trend of steam and air are similar, however, compare to air, steam has a 49.2 % higher average Nusselt number and 31.8 % lower friction factor under the same inlet mass flow rate. Under a low mass flow rate condition, the steam cooling shows a smaller maximum temperature difference and better uniform cooling performance.
