Optimal Power System Dispatch Strategy for Reducing Carbon Emissions

Strategic Insights -

A recent study has proposed a novel strategy for power system dispatch that takes into account the flow of carbon emissions and large consumers. The research, conducted by researchers at the University of Rhode Island, aims to reduce both the operation cost of the power grid and the power utilization cost of large consumers. By applying the optimal power flow (OPF) method and considering the direct purchase of power by large consumers, the study's simulation results indicate a significant reduction in carbon emissions.

Key Takeaways:

  • The study proposes a power system optimal dispatch strategy that considers the flow of carbon emissions and large consumers, aiming to reduce both the operation cost of the power grid and the power utilization cost of large consumers.
  • The improved carbon emission flow theory is used to allocate power loss to the load side, allowing for a more accurate simulation of the power grid.
  • The OPF method is applied to solve the problem, enabling the optimization of the cost of both large consumers and the power grid.
  • The study analyzes the effects of the price of carbon emissions and the price of electricity from normal generators and low-carbon generators on the optimal dispatch.
  • The simulation results show that the proposed strategy can significantly reduce both the operation cost of the power grid and the power utilization cost of large consumers.
  • The study highlights the importance of considering the direct purchase of power by large consumers in power system development.
  • The researchers suggest that the proposed strategy can benefit from the carbon emissions trading market.

Statistics:

  • The study uses an IEEE 30-bus system to test the performance of the proposed strategy.
  • The simulation results indicate a significant reduction in carbon emissions through the optimal dispatch strategy.
  • The price of carbon emissions has a significant impact on the optimal dispatch, with a 10% increase in carbon price leading to a 5% reduction in power utilization cost.
  • The price of electricity from low-carbon generators has a positive impact on the optimal dispatch, with a 10% increase in price leading to a 2% reduction in carbon emissions.
