Title: Research on Coordination Mechanism of regional electricity hydrogen coupling comprehensive energy flexibility and optimization of cross domain system for deep decarbonization

Abstract:

Under the background of low-carbon development, the trend of re electrification and low-carbon development of urban energy consumption is obvious. With the development of new industries such as integrated circuits and new infrastructure such as 5g and data centers, China will promote a new round of rapid growth of regional energy. As a major city receiving external power, Shanghai will face large-scale distributed energy grid connection, and the proportion of superimposed terminal power consumption will grow rapidly. The safety and reliability of urban distribution network will face great challenges. The "electricity hydrogen" coupling system is considered to be an important component of future energy that can break through the limitations of renewable energy development and achieve the power and electricity balance of multi-level power grids. It is an important way to realize the green and low-carbon transformation of terminal energy, and expand the scope and depth of power substitution. This paper aims to meet the needs of deep power substitution and decarbonization on the user side, excavate the flexibility of electric hydrogen coupling in new power systems, adjust the margin, and expand typical electric hydrogen coupling scenarios such as "traffic power, industrial heating, building heating" to achieve deep decarbonization in the process of terminal energy re electrification. This paper puts forward the evolution path of regional electric hydrogen coupling, and scientifically arranges sufficient electric hydrogen two-way interactive conversion devices in the space-time of the power network, so as to improve the stability of the green distribution network system. This research work will provide a decision-making theoretical reference for actively supporting the new power system and building a low-carbon, green, hydrogen electricity coupled deep decarbonization energy supply system.

Title: Explosions of ball lightning inside enclosed premises

Abstract:

Sooner or later, the life of ball lightning ends. Having exhausted the supply of energy, it can “dissolve” in the air without a trace or disappear, leaving traces on the painted floor in the room [1, 2]. But in the case of a “violent” death, ball lightning does not have time to use up its energy reserve, and the consequences of its explosion can become significant. The death of ball lightning can occur when it collides with some obstacle. At the same time, a sheaf of sparks flies out of it - elements of its energy core. On May 27, 2013, ball lightning exploded inside a log house in the village of Mogsokhon in Buryatia (Russia). The wall of the house fell out from the explosion, windows and doors were squeezed out, sheets of slate on the roof were torn off (see Fig.). Surprisingly, the owner, Rada Sandanova, who was next to the ball lightning at the time of the explosion, suffered, but remained alive. The energy of this ball lightning, estimated from the equivalent effect of an explosion of TNT, turned out to be about 30-130 MJ [3]. The literature describes similar cases of explosions of ball lightning inside the premises, which caused great destruction. Brand [5] had described the aftermath of a ball lightning explosion on 22 March 1914 in a church in the village of Poggio tre Crosi. The explosion squeezed out the doors, split the pillars of the windows, destroyed the facade of the church. In the summer of 1938, in the Vologda Oblast (Russia), ball lightning the size of a soccer ball exploded inside a smithy. As a result, the wall of the smithy fell to the ground [1]. The witness, being inside the smithy, survived. In August 1924, in the village Gvozdki (Russia), during a thunderstorm, ball lightning penetrated into the hut through the chimney [5]. Having exploded on the stove next to a dough tub, it threw the tub and the boy sitting by the window into the street at a distance of about 20 meters. The boy was not hurt. These features of the action of ball lightning can be explained on the basis of the electrodynamic model [6]. According to this model, ball lightning has an electric charge Q of 10^-3 - 10^-1 C. The charge is inside a spherical shell of radius R, consisting of water molecules, and stretches it with the force F_em = Q²/4πε₀R². Opposite to this force is the shell compression force caused by the polarization of the shell material, F_sh = 2σaQ/ε₀R, where σ = 1 C/m² is the surface charge density of dipoles (water molecules), and a is the shell thickness. When the shell breaks, charge carriers settle on the walls of the room and push them apart from the inside. According to the observation, in 1938, ball lightning with a radius of 16 cm with a shell thickness of a = 2.5 cm exploded in the smithy. Based on the equality F_em = F_sh, we find the charge of ball lightning Q_bl = 8πσaR = 0.1 C. Such a charge, deposited on the wall of a sphere with a radius R_k = 2 m, presses on its surface with a force F_k = Q_bl²/4πε₀R_k² = 2.25·10⁷ N.

For the case of a ball lightning explosion at the furnace [5], ​​it can be assumed that ball lightning with a charge of 3.5·10^-3 C transferred a charge of 3.5·10^-5 C to the dough tub. Starting from this charge, the tub acquired a speed sufficient to fly out of the window of the hut. So, it can be concluded that the effect of a ball lightning explosion differs from that of a domestic gas explosion. In the latter case, destruction is caused by a shock wave. In contrast, the charge of ball lightning “smoothly” pushes
