Wind solar water and thermal energy storage power generation system

How do integrated energy systems work?

As shown in Fig. 1, the primary energy supply of the integrated energy system is based on photovoltaic and wind power, relying on a combined wind-solar power generation system to fully harness solar and wind resources, converting them into electrical energy to support the power load of the complex.

Why do thermal power units need energy storage systems?

As a result, thermal units prioritize dispatching ones with lower carbon emission factors, and the absence of energy storage systems may lead to thermal power units taking on all peaking tasks, and requiring more frequent adjustment of output to consume wind and solar in power generation.

What is the integration rate of wind and solar power?

The integration rates of wind and solar power are 64.37 % and 77.25 %, respectively, which represent an increase of 30.71 % and 25.98 % over the MOPSO algorithm. The system's total clean energy supply reaches 94.1 %, offering a novel approach for the storage and utilization of clean energy. 1. Introduction

Why should energy storage systems be integrated with carbon trading mechanisms?

Moreover, when combined with carbon trading mechanisms, energy storage systems can optimize the internal output plan of the power generation system, thereby maximizing the consumption of wind and solar power and minimizing the cost of power generation.

How are wind and solar power generation data used?

The annual wind and solar power generation data are used to estimate the kernel density estimation function of wind and solar power generation, taking into account seasonal and temporal variations, that enables the determination of the corresponding mathematical expectations of wind and solar power generation.

What percentage of energy is produced by wind and solar?

As illustrated in Fig. 7, on the generation side, wind and solar power account for 64 % of the total energy produced, with respective shares of 31.5 % and 32.5 %, serving as the primary energy sources for the system.
