New energy power system operation security evaluation based on the SWOT analysis

Area of Science:

• Power Systems Engineering
• Renewable Energy Integration
• Operations Research

Background:

• Grid connection of new energy is vital for clean energy promotion but introduces significant power grid operation security risks, including frequency and voltage stability issues.
• Assessing the operational security of new energy power systems is essential for sustainable development and mitigating potential crises.

Purpose of the Study:

• To assess the operation security prospective of the new energy power system in HM, China, using a comprehensive analytical framework.
• To identify and prioritize effective strategies for enhancing the security and stability of power grids with high new energy penetration.

Main Methods:

• Employing SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis to define 24 evaluation factors and 8 improvement strategies.
• Utilizing the fuzzy-Analytical Hierarchy Process (fuzzy-AHP) method to determine the weights of SWOT factors.
• Applying the fuzzy-Multi-Attribute Comprehensive Assessment System (fuzzy-MARCOS) approach for strategy selection and ranking.

Main Results:

• New energy resources in the HM area show significant development potential but large-scale grid connection presents operation security challenges.
• The fuzzy-MARCOS method effectively ranked 8 improvement strategies, with A2, A6, and A5 identified as the most critical.
• The top strategies include improving technical infrastructure for efficient electricity production, developing local loads to reduce transmission risks, and leveraging government incentives to refine energy policies.

Conclusions:

• The proposed methodology, combining SWOT, fuzzy-AHP, and fuzzy-MARCOS, is effective for evaluating power system operation security.
• Prioritizing strategies focused on technological enhancement, localized energy infrastructure, and supportive government policies is crucial for secure new energy integration.
• Addressing operation security concerns is paramount for harnessing the full potential of new energy resources and ensuring national energy security.
