Abstract:

There is a correlation between solar irradiation and electricity demand, and thus grid could deploy more photovoltaic (PV) electricity to substitute for coal at the peak load time. The gradually decreasing cost will make PV generation competitive when satisfying the peak load demand. With the annual irradiation and the regional grid load data record, the potential of the grid to accommodate PV electricity was analyzed without deploying storage or decreasing the base-load units output. The result showed that to reduce the utilization factor from 100％ to 95％, the PV electricity cost only increased by 4.8％, but the penetration of PV electricity increased from 3％ to 7％. It’s illustrated that even without storage, the PV generation could still satisfy a remarkable portion of the grid electricity demand.
