Abstract
The paper considers effectiveness of a penetration of renewables into potential Northeast Asia power system interconnection. Renewables are currently in the mainstream of expansion of energy sector in the world and in Northeast Asia, particularly. Formation of NEA power interconnection will increase utilization of variable and poorly predictable renewable generation. Economic incentive for penetration of renewables, like CO2 emission tax, is studied. The study revealed that quite significant tax is needed to be imposed to induce non-fossil fuel generation capacities, including renewable ones, to be added to power systems.
Highlights
Electric power integration with the creation of interstate electric ties (ISETs) and large power grids, including the interstate ones (ISPGs), as well as large-scale use of renewable energy sources (RES) are among the dominant trends in the global power sector
We have studied the prospects for expansion of RES in the framework of a potential ISPG in Northeast Asia (NEA) with optimization of their capacity and power along with the capacity and power of traditional
This research continues the previous studies of the authors aimed at investigating formation of ISETs and ISPG in Northeast Asian region with deeper consideration given to environmental issues and renewable energies, which is a mainstream of energy and power development in the world and NEA, as was noted above
Summary
Electric power integration with the creation of interstate electric ties (ISETs) and large power grids, including the interstate ones (ISPGs), as well as large-scale use of renewable energy sources (RES) are among the dominant trends in the global power sector. It is necessary to study scenarios of the future formation of ISETs and ISPG in the region, with large-scale penetration of RES. This meets the requirements of the Paris agreement on the constraint of emissions of carbon dioxide (CO2) and other greenhouse gases [1], ratified by Russia in 2019 [2]. The results of the study showed that RES can take a important place in the potential electricity balance of NEA, and the ISPG will contribute to their more complete and effective utilization to cover the joint electric load of consumers in the region
