Coordination and Consumption Method of Multi-regional Interconnected Power System with Wind Power

New energy which is low-cost, clean and environmentally-friendly has been widely used due to the rapid increase of energy demand and environmental pollution caused by traditional fossil energy. However, the volatility, randomness and intermittence of distributed energy bring great challenges to the power system. This paper proposed a multi-scenarios decentralized coordination method of multi-regional interconnected power system with wind power, which can achieve the purpose of multi-regional coordinated consumption of wind power in the power grid. Firstly, the economic dispatch model of certain scenario under wind power forecasting scenario was established, and the analytical target cascading method was used for decentralized coordination and optimization of the model. Secondly, to modify and optimize the the economic dispatch model of certain scenario, the uncertain scenarios of wind power were generated by multi-scenarios method, which formed the economic dispatch model of error scenarios. Finally, the optimal generation scheduling scheme of the power network was calculated by the cyclic iteration of decentralized coordination optimization and error correction optimization. The example results showed that proposed coordination and consumption method of multi-regional interconnected power system with wind power can solve the problems of uncertainty of wind power and the large-scale wind power consumption effectively.
