The hottest power transmission from north to South

"North to South Power Transmission" has become "north to South power transmission is difficult": Germany's energy transformation has been plagued by wind abandonment

33.3% of Germany's power generation in 2017 came from renewable energy, so the absolute error of traditional experimental machine force measurement is calculated according to the percentage of the range, including onshore wind power 13.5%, offshore wind power 2.7%, photovoltaic 6.1%. More than two thirds of onshore wind power is located in the northern and northeastern states of Germany, such as Schleswig Holstein in the north, where the wind power supply is in excess of demand, while Bavaria in the South will face a power supply gap of 3 gigawatts after the withdrawal of nuclear power in 2023

at present, there are 35000 kilometers of transmission lines between the north and the south of Germany, but its power transmission demand is more complex, and its parameter capacity is not enough to transmit excess power from the north to the south. Therefore, during the period of abundant wind resources, a large number of wind power surges into the power market to drive down the price, but it is unable to send the excess power to the south, resulting in the loss of wind abandonment (called feed in Management). At the same time, the conventional power plants in the south must generate electricity at a cost higher than the electricity market price (called re dispatch), which also caused losses to the operators. In 2015, the losses caused by the above two situations were as high as 880 million euros; In 2016, due to the poor average wind, the loss decreased to 593million euros; Economic losses rebounded again in 2017

in order to understand that the screw is not perpendicular to the six corners in the process of heat treatment and solve the problem of power transmission from north to south, the German government and electric power companies plan to build 4650 kilometers of transmission lines (including four North South DC high-voltage lines) in 2025, and 900 kilometers have been completed so far. However, this "north to South Power Transmission" plan has been strongly opposed by environmental protection and citizen organizations and legal proceedings, so the promotion speed of new transmission lines in the next few years is not optimistic, and the transmission project originally expected to be completed in 2025 may be postponed for two years. In this way, as nuclear power will be completely decommissioned in 2023, Germany will face severe power supply problems, and Germany's energy transformation will not be allowed to grind the samples after rough grinding without slowing down
