Abstract:
In order to coordinate and control all kinds of distributed energy in distribution network more effectively and adapt to the core concept of active distribution network, an active distribution network transactional energy minimization method based on market-based control is proposed. Firstly, combining the idea of market-based control with the characteristics of various distributed energy sources in the active distribution network, a market control-based distribution network transactional energy minimization method is proposed. Then, considering the uncertainty factors of renewable energy consumption and active load and the differences between different subjects in distribution network, energy bidding models of distributed energy, adjustable load and energy storage system are established respectively. Moreover, a distribution network energy trading model is established, which realizes the optimization of distribution network energy and the balance of power supply and demand. Finally, an example is given to verify the effectiveness of the energy minimization method in blocking management of distribution network, increasing the consumption rate of renewable energy and economy.
