The multi-energy complementary ecosystem (MCE) has the advantage of making full use of renewable energy and removing the dependence on carbon-based energy, which can achieve maximum efficiency of energy utilization and promote low-carbon development [ 3 ].
The methodology of this review work could be divided into four steps. The first step was to determine the theme of the review, which is multi-energy complementary power systems based on solar energy. The second step was to search and classify the relevant references.
In the study, multi-energy complementarity is considered, based on demand response, and a Multi-energy Complementation (MEC) optimal dispatch model is established based on Conditional value at risk (CVaR), and finally the energy system optimal dispatch test simulation evaluation under different circumstances is carried out.
Considering the issues of energy supply and environmental protection, clean energy has become the strategic basis for China’s development. So, the multi-energy complementation (MEC) comprehensive energy system has gradually been widely used (Nguyen and Huynh 2019).
To cope with this issue, a novel comprehensive evaluation framework for multi-energy complementary ecosystems is proposed in this study. First, a 5D comprehensive evaluation criteria system, including environment, economy, technology, safety and systematicness, is constructed.
Combined with the normalized information matrix, the pairwise comparison of multi-energy complementary cases is carried out and the pairwise difference degree of each index is measured based on preference functions. The calculation results are shown in Table 7.
In the background of the large-scale development and utilization of renewable energy, the joint operation of a variety of heterogeneous energy sources has become an inevitable development trend. However, the physical characteristics of different power sources and the inherent uncertainties of renewable energy power generation have brought difficulties …

Theoretically, economic and environmental properties of MECSs have been effectively upgraded through optimization, but a pitfall has loomed. After optimization, the capacity of renewable energy equipment is always increased and that of primary energy equipment is always reduced, thus decreasing the redundancy of energy supply [18] may pose risk to …
Multi-energy complementary renewable energy system is an efficient energy supply system based on thermoelectric-gas-storage coupling technology to realize full renewable energy supply in local regions, with biomass power generation as the basic energy, wind, light and storage as the supplement. Since 2000, China has promulgated a series of ...
