Photovoltaic abandoned light energy storage solution

How does pumped storage affect the cost of a photovoltaic system?

Table 7 shows that the capacity of pumped storage is directly proportional to the cost, but inversely proportional to the reliability of the pumped storage/wind/photovoltaic complementary system, the volatility between the system and the load, and the output of wind and photovoltaic abandoning.

Where are photovoltaic projects being built?

Chevron Questa has built photovoltaic projects in an open-pit mine in New Mexico ( 7 ). Photovoltaic projects have also been initiated in the abandoned mines in Meuro and Schipkau, Germany ( 8 ). China has almost 13,000 abandoned coal mines spread across the country ( 9 ).

Should a multi-energy complementary power generation system be abandoned?

Authors to whom correspondence should be addressed. In multi-energy complementary power generation systems, the complete consumption of wind and photovoltaic resources often requires more costs, and tolerable energy abandonment can bring about the more reasonable optimization of operation schemes.

Why is wind and light abandonment a problem?

This is due to the fact that the amount of fresh energy is too great, thermal power units’ and pumped storage power stations’ adjustment capacity is constrained, and the load absorption limit has been reached, forcing the power system to generate wind and light abandonment.

What happens if an electrolyser uses abandoned wind and photovoltaic output?

When the abandoned wind and photovoltaic output is between the minimum power (P elmin) and the maximum power (P elmax) of the electrolyser, the electrolyser uses the abandoned wind and photovoltaic output as the power to produce hydrogen, and the lead-acid batteries do not work.

How pumped storage wind–solar–thermal combined power generation system compromise operation scheme works?

The pumped storage wind–solar–thermal combined power generation system compromise operation scheme was given by the MOPSO algorithm by using the reasonable energy abandonment method, which is more in line with the actual operation needs of the project and can effectively reduce the operating cost.
