Regional Multi-Energy System Planning with Considering the Correlation between New Energies' Output

Nowadays, new energy is an important tool to deal with global energy shortage crisis and environment pollution. The volatility and uncertainty of intermittent new energy injection will dramatically impact the economy of regional planning and system operation. Thus, it is vital to accurately describe the volatility of new energy and construct the reasonable new energy capacity optimization model. A novel regional new energy planning is proposed to accurately calculate the new energy capacity, first, analyzing the correlation between regional new energies, and then, the typical minute-level new energy output scenarios are derived by fuzzy C-means (FCM), finally, an double-layer new energy optimization model is built with taking net value of whole life cycle of new energies including WT and PV as the upper objective function and system volatility rate as the lower objective function, respectively. The regional new energy planning can achieve a tradeoff between system volatility and planning economy. The simulation results validate the reasonability of the proposed double-layer model.
