Regional energy planning ideas from a zero-carbon perspective

 

“Regional energy planning ideas from a zero-carbon perspective” provides a clear path and method for regions to achieve carbon neutrality goals. Through energy conservation and emission reduction, clean substitution, local energy development, energy supply and demand matching, regional collaborative development, multi-network synergy, and risk management, carbon emissions in the region can be effectively reduced, and sustainable regional development can be promoted.

1. Energy conservation and emission reduction and clean substitution: a two-pronged approach

Energy conservation and emission reduction: Reduce carbon emissions by improving energy efficiency and reducing energy consumption.

Industrial sector: Optimize production processes, use energy-efficient equipment, and improve energy management levels.

Building sector: Promote energy-efficient building technologies, improve building energy efficiency standards, and strengthen building energy efficiency renovations.

Transportation sector: Develop public transportation, promote new energy vehicles, and optimize the transportation travel structure.

Clean substitution: Transform the energy structure by using clean energy to replace fossil fuels.

Renewable energy: Prioritize the development of renewable energy sources such as solar, wind, and hydropower, and increase the proportion of renewable energy in energy consumption.

Hydrogen energy: Promote the development of the hydrogen energy industry and use hydrogen energy as an important component of the future energy system.

Electricity substitution: Promote electricity substitution and use electricity as the main form of terminal energy consumption.

2. Local energy supply: maximizing potential

Local renewable energy resources: Based on regional resource endowments, focus on developing renewable energy resources such as wind energy, solar energy, geothermal energy, and biomass energy. Conduct resource assessments to determine the maximum development potential and development sequence.

High-efficiency conversion path: Based on the principle of maximizing the utilization of renewable energy, select the optimal conversion path to improve energy conversion efficiency. For example, prioritize the use of photovoltaic power generation, followed by wind power generation and geothermal energy, and try to avoid the direct use of biomass energy.

3. Energy supply and demand matching: optimal allocation

Multi-objective optimization: Establish a multi-objective function with total carbon emissions and economic efficiency as the goals to determine the overall solution with the lowest carbon emissions and the best economic efficiency.

Mixed integer linear programming model: Based on boundary conditions such as equipment conversion efficiency, investment, and operating costs, build a model to optimize the energy allocation scheme.

8760h operation optimization: Consider the energy supply and demand situation at different time nodes to conduct operational optimization and ensure stable and reliable energy supply.

4. Efficient energy allocation: multi-network synergy

Through the synergy of power grids, hydrogen energy grids, heating and cooling grids, and gas grids, break down the barriers between various types of energy and achieve efficient energy allocation. Utilize electricity-heating and cooling, electricity-hydrogen, and gas-electricity network coordination to optimize energy conversion paths and improve energy utilization efficiency.

5. Energy security: risk management

Identify risk factors: such as extreme weather, international politics, and emergencies.

Incorporate risk management into planning: Consider energy security factors in the planning process and develop countermeasures.

Inter-regional mutual assistance: Improve the overall risk resistance capacity of the region.
