Wind power and photovoltaic power generation and carbon trading

Can energy storage and carbon trading reduce the purchase of electricity?

Upon comparing Fig. 7 (c) with the other three scenarios, it is evident that the integration of energy storage systems and carbon trading mechanisms can significantly increase the on-grid energy of wind and solar power and reduce the purchase of electricity.

Can power storage and carbon trading promote collaborative dispatch on hybrid power?

The results showed that incorporating power storage and carbon trading simultaneously can effectively promote the collaborative dispatch on hybrid power with assistance of thermal, improve utilization rate of wind and solar power, while also reducing the costs associated with power generation. 1. Introduction

Are solar PV and wind energy going west-to-East?

Our results also show a notable west-to-east interhemispheric shift of wind energy by the mid-twenty-first century, under the two global carbon-neutral scenarios. Both solar PV and wind energy are projected to have a greater temporal stability in most land regions due to deep decarbonization.

How does weather affect solar PV & wind energy generation?

It is well known that solar PV and wind energy generation are heavily influenced by weather fluctuation, which yields strong variability at various time scales. Understanding the variability of renewable energy is vital for coordinating compensatory energy sources and storage in order to secure a stable energy supply 66, 67.

How to generate P2G output from a wind turbine & photovoltaic (wt-PV)?

Firstly, a 24-h joint wind turbine and photovoltaic (WT-PV) output scenario generation method is proposed based on the time-varying Copula function. Secondly, the introduction of carbon capture technology (CCT), electrolyzer (EL), methane reactor (MR) and hydrogen fuel cell (HFC) refines the operation process of p2g into two stages.

What is the power-use efficiency of PV and wind power plants?

By considering the flexible power load with UHV and energy storage, the power-use efficiency for PV and wind power plants is estimated when the electrification rate in 2060 increases from 0 to 20%, 40%, 60%, 80% and 100% (a) and the power generation by other renewables in 2060 increases from 0 to 2, 4, 6, 8 and 10 PWh year −1 (b).
