考慮P2G多源儲(chǔ)能型微網(wǎng)日前最優(yōu)經(jīng)濟(jì)調(diào)度策略研究
[Abstract]:Due to the increasing installed capacity of new energy generation and the unsynchronized construction of power grid, the phenomenon of abandoned wind and light appears, which results in the waste of energy. By means of integrated energy system, multivariate absorption technology and multiple storage technology can increase the local absorption of renewable energy and improve fan utilization ratio. This paper first introduces the principle of electropneumatic (power to gas,P2G) technology, and then, based on the micro-grid energy hub model, divides the multi-source energy storage microgrid system with P2G into three parts: supply side, conversion module and load side. On the basis of this, a pre-day optimal scheduling model for micro-grid systems based on economic optimization is established to investigate the potential of P2G to absorb renewable energy. Finally, three different scenarios of micro-grid system are used to verify the results. The results show that P2G can improve the phenomenon of abandoned wind greatly and has a good application prospect.
