“…Literature [9] integrated phase-change material buildings as heat storage devices for heat storage, reducing system heat supply and forced electricity output. Literature [10][11][12] proposed a new type of solar heat and power cogeneration system composed of solar collectors to alleviate the heating load of buildings. Literature [13] used cogeneration units, auxiliary heat boilers, and heat pumps to coordinate heat supply and improve the structure of traditional cogeneration units.…”

Electric-heat coupling characteristics of a cogeneration system and the operating mode of fixing electricity with heat are the main reasons for wind abandonment during the heating season in the Three North area. To improve the wind-power absorption capacity and operating economy of the system, the structure of the system is improved by adding a heat storage device and an electric boiler. First, aiming at the minimum operating cost of the system, the optimal scheduling model of the cogeneration system, including a heat storage device and electric boiler, is constructed. Second, according to the characteristics of the problem, a cultural gene algorithm program is compiled to simulate the calculation example. Finally, through the system improvement, the comparison between the conditions before and after and the simulation solutions of similar algorithms prove the effectiveness of the proposed scheme. The simulation results show that adding the heat storage device and electric boiler to the scheduling optimization process not only improves the wind power consumption capacity of the cogeneration system but also reduces the operating cost of the system by significantly reducing the coal consumption of the unit and improving the economy of the system operation. The cultural gene algorithm framework has both the global evolution process of the population and the local search for the characteristics of the problem, which has a better optimization effect on the solution.

Solar technologies are an efficient means of addressing environmental pollution and climate change challenges. In this study, an organic Rankine cycle (ORC) system driven by solar evacuated glass tubes named solar water power generation system (SWPG) was experimentally investigated to explore the performance of the SWPG system in powering buildings. For ORC, a new mixture called TD-3 was introduced for the experiment after comparing the thermodynamic characteristics of five working fluids using REFPROP software. The solar radiation intensity was simulated for solar collectors to determine the best installation angle of the evacuated glass tubes to be 30° in Tianjin, China. The power generating efficiency was tested as high as 4.5% at 1:00 pm on July 15. The optimization of operating parameters and the modification of generating equipment contributed to the increase in power generation. The SWPG system could achieve an optimal power output when the system guaranteed a small superheat and no more than 3°C subcooling using the TD-3. The transmission ratio between the generator and expander also impacted power generation that the ratio of 2:1 helped optimize the power generation.
