The invention provides a two-sided photovoltaic power generator, comprising a two-sided photovoltaic power generating component and a light reflecting element; one side of the two-sided photovoltaic power generating component facing to sunshine is positive face while the other side is back face; the light reflecting element is arranged at the back face of the two-sided photovoltaic power generating component, and the light reflecting element is provided with a light reflecting face to reflect sunray to the back face of the two-sided photovoltaic power generating component; the light reflecting face is a convex face towards the two-sided photovoltaic power generating component. Through arranging the light reflecting element at the back face of the two-sided photovoltaic power generating component and reflecting sunray to the back face of the two-sided photovoltaic power generating component by the light reflecting face of the light reflecting element, the light utilization efficiency is improved, the power generation efficiency is improved, and the economic benefit is further increased.

The invention discloses a scheduling optimization method for an active power distribution system in an industrial park considering the peak-shaving demand of the power grid. The photovoltaic power generation unit PV, the all-vanadium liquid flow battery energy storage system VRB and the industrial load are used as industrial loads to participate in considering the peak-shaving demand of the power grid. The dispatching unit of the active power distribution system in the park establishes the physical model of each dispatching unit; the dynamic dispatching optimization problem of the active power distribution system in the industrial park considering the peak-shaving demand of the power grid is established as a DTMDP model; the Q-learning algorithm based on simulated annealing is used to carry out the DTMDP model Strategy solution, the obtained optimization control strategy is used to guide the system to choose a reasonable action plan in the actual operation process, and realize the system scheduling optimization. The invention can effectively solve the peak-shaving demand problem of the power grid under the consideration of the randomness on both sides of the source and load, promote the on-site consumption of new energy, and improve the operation economy of the active power distribution system and the operation stability of the power system.
