Research on the development of distributed power generation strategy through differential scheduling requirements

Abstract

The development of high-penetration photovoltaic power generation is an important measure to realize the energy revolution. With the continuous increase of photovoltaic capacity, the electricity generated by distributed photovoltaic can’t be absolutely integrated to power grid in the future. It is necessary to improve the scheduling requirements for photovoltaic equipment so that the system can be in safe operation. First of all, four scheduling requirements are set for the grid integration of photovoltaic equipment from the perspective of grid scheduling, which is characterized by differentiated scheduling of power and electricity between the micro-grid composed by photovoltaic equipment, energy storage and utility. Then, the capacity optimization planning model of the photovoltaic and energy storage system is established with the minimum power supply cost of the microgrid as the objective function. Finally, through the case study, it is found that industrial and commercial enterprises have the economic motivation to invest in the construction of the photovoltaic and energy storage microgrid, which will strengthen confidence in promoting the rapid development of photovoltaic power generation.
