Optimal Dispatch of Microgrid Based on Situation Awareness

Microgrid can allow a lot of renewable energies to penetrate into power system and achieve maximum utilization of existing energies and demand-side management. Existing study focus on the uncertainty of renewable energy and load, but the microgrid risk status is rarely considered. The paper proposes an microgrid optimal dispatch model based on situation awareness (SA). According to the three levels of SA, the uncertainty model in microgrid is established, the risk coordination constraints are analyzed, and the risk cost is proposed. The proposed model takes two cases of loss of load and resource wastage into consideration to cover most possible impacts of potential risk in microgrid. A typical microgrid is analyzed to find optimal decisions and to minimize the comprehensive risk. The validity of the proposed model and the impact of confidence level and tolerance margin is demonstrated through case study.
