Distributed PV grid system
Distributed basic principles: is mainly based on the surfaces of buildings, the nearest solve the user's
problem of electricity through the power grid to realize the difference between the compensation and
outgoing.
Distributed Advantageļ¼Solar power is the user side, the local power supply load, regarded as the load, can effectively reduce dependence on the power grid and reduce line losses;Full use of the building surface, it can simultaneously photovoltaic cells as building materials, effectively reducing the footprint of photovoltaic power plants;And effective interface to the smart grid and microgrid, flexible operation, under appropriate conditions can be run independently from the power grid.
Centralized PV Grid System
Centralized basic principle: take advantage of abundant solar energy resources and relatively stable desert
regions to build large photovoltaic power plants, high-voltage transmission system provides access to the
power grid load.
Centralized Advantageļ¼Since the site is more flexible, photovoltaic output has increased stability, and make full use of the positive characteristics of solar radiation and peaking power load, play a role clipped;Run more flexible with respect to distributed PV can be more easily reactive power and voltage control;Short construction period, Environmental adaptability, no water, coal and other raw materials transportation security, low operating costs, ease of centralized management, little by space constraints, you can easily achieve expansion.
