In other countries, Germany, and Spain network by more than 220,000 volts and transnational interconnection line interconnected with adjacent countries have achieved strong, wind power energy dissipation is satisfied that a strong support by the European grid. At present, mainly composed of decentralized wind power distribution network access to large Department European countries increasingly face wind power development and utilization of bottleneck, proposed for the realization of the EU in 2020 the proportion of renewable energy in total primary energy reached 20% magnificent goals, renewable energy in the future the EU will gradually shift the focus to the development of offshore wind power and solar desertification. Therefore, in order to access and sending of renewable energy at long intervals, European countries presented the construction of large scale offshore wind power and solar access system of inter-regional power grid. Denmark power grid and Norway, and Sweden and Germany achieved through 14 tie-line interconnect, Norway and other countries have rich hydropower resources to display their "battery", Denmark had a good wind power regulation. National Division, countering the new energy of the future demand for electricity.
Our wind resources mainly in the West, East is a major electricity users, distance between the two places, so meeting the large-scale grid-connected wind power and objective require that the network should have sent a strong grid structure, strong power transmission capability and advanced control technologies. Wind energy resources in China and Central reverse distribution of load, this basic national condition determines the need to build a high capacity, long-interval of energy transport channel, achieving optimal allocation of wind power at the national level and absorptive.
This also determines the current must change the mode of power system development in China, building strong and reliable power grid, relying on wind power and mass transportation across regional power grid optimization is the promotion of large-scale wind power development and the future absorptive objective needs and trends. Can be predicted that in large-scale renewable energy exploitation in the future, driven by, inter-regional power network delivering services to the entire energy and optimized allocation of, and make great contributions in that regard. Reasonable adjustment of regional energy solve the various problems caused by unbalanced distribution.
