Space astronomical telescopes must test the image stabilization accuracy of their image stabilization system prior to entering the orbit. According to the position characteristics of the fine guidance sensor of telescopes required by the China National Space Administration, a simulation model of moving guide stars is proposed in this study to test the image stabilization accuracy of space telescopes. The simulation model for synchronous moving guide stars is based on the principle of mutual collimation of the diagonal field of view of the optical system of telescope. Realize the multi-field moving guide stars with high synchronization accuracy simulated by the same target source. Compared to traditional methods, this method requires simple manufacturing and has high flexibility. The error sources affecting the simulation accuracy of the moving guide stars are analyzed, and an error model is established. Analysis results show that the simulation accuracy of the moving guide stars can reach

The rapid development of photovoltaics (PVs) and load caused a significant increase in peak loads and peak‐valley differences in rural distribution networks, which require load peak shifting and line upgrading. Large peak‐valley differences also bring challenges on the safe operation of the utility power grid. Considering the integration of a high proportion of PVs, this study establishes a bilevel comprehensive configuration model for energy storage allocation and line upgrading in distribution networks, which can reduce peak loads and peak‐valley differences. In the upper level, a minimum annual planning cost is obtained by developing the installation capacity of centralised energy storage in transformer stations, the installation location and capacity of decentralised energy storage on lines and a scheme of line upgrading. In the lower level, the minimum total annual operation cost of the distribution network is obtained by developing an optimal scheduling for the centralised energy storage in transformer stations and decentralised energy storage on lines. Simulation results show that compared with the conventional energy storage planning strategy, the configuration investment can be reduced by 467.66 million yuan at least with the proposed strategy.
