Photovoltaic (pv) power generation has excellent power quality, can be barrier-free straight

Solar-thermal power generation with conventional fossil energy in the thermal power generation principle is the same, is through the Rankine cycle, Brayton cycle or Stirling cycle converts heat energy to electricity, direct output alternating current (ac), don't like solar or wind power need inverter switch

the solar-thermal power generation with the traditional fossil energy principle is the same in terms of thermal power generation. It through the Rankine's circulation, brayton cycle or Stirling cycle will heat energy into electricity, alternating current (ac) and direct output. It does not need to like solar or wind inverter transformation. Transmission technology is relatively mature, high stability, and the current domestic power grid connection is more convenient, power quality is good. It can be used to store energy, adjust peak, continuous power generation. The shape of the power grid load curve is similar to the natural curve of the solar power during the day. Load increases with time in the morning, decrease with time in the afternoon. As a result, solar power grid is natural peak loads. Load rate according to the heavy load difference between day and night power grid to determine, generally 10 - 20%. Due to heat, easy to store all the solar-thermal power plants have a certain ability of peak shaving and scheduling is achieved by heat transfer power buffer and smooth, and can deal with the short-term instability of solar energy; Energy storage is the bottleneck of renewable energy development. Practice proves that the accumulation of heat of electric heat storage is obviously better than the efficiency and economy of pumped storage. Solar-thermal power stations with special heat storage device, not only can supplement energy during startup and partly cloudy, guarantee the stable operation, also can realize sunset 24-hour power generation, also can undertake according to the requirements of load and power grid peak shaving and scheduling. Under the scale effect, cost advantage. Due to the thermoelectric conversion link the same as the heat energy, solar energy light heat generation and heat also has significant economies of scale, is better than that of wind power and photovoltaic power generation. As technology advances and the expansion of industrial scale, solar-thermal power generation will soon close to or even lower than the cost of traditional fossil energy to produce electricity.
