Pingtan is located in a coastal monsoon zone with large seasonal changes in precipitation, so hydropower is affected during the dry season (fall and winter). The biggest disadvantage of wind power generation is its instability. The so-called complementarity means that during seasons with strong winds, when runoff is low and hydropower is insufficient, wind power is enhanced. Therefore, the complementary reason should be that the wind is strong in autumn and winter and the runoff is small. Therefore, choose B
Wind power is unstable and wind power generation must adapt to this change. It produces electricity when the wind is moderate, but does not produce electricity when the wind is strong and hourly. some statistics, among the 8,760 hours throughout the year, the number of hours that can produce electricityquoted is The time is only about 2,000 hours;
How to solve the continuity of power consumption and the discontinuity of wind power generation depends on the advantages of "power system". The power system uses the power grid to connect different types of systems consisting of power plants and users at various locations, provided that the total power generated in the system can be greater than the total power generated. the total electrical energy consumed, there will be no power outage; when wind power in one place can't produce electricity, maybe water conservation can just produce electricity, and maybe solar power will be the perfect solution, maybe be tidal power stations. can generate electricity, perhaps wind power plants in other regions can also generate electricity, and finally there arethermal power plants and nuclear power plants as backup, because all power plants are connected to each other and "interact with each other", so a continuous power supply is not possible. Problem;
The electricity network does not need to undergo any particular transformation for this purpose. The transformation of the power grid to improve the reliability of power supply and reduce the total social energy consumption has never stopped in the future. deepening the construction of smart grids, the power grid will be more stable, economical, safe, flexible and efficient.
