Testing Methods

Standards-based laboratory testing forms the evidentiary core of the evaluation. Accredited third-party laboratories apply calibrated instrumentation and documented test procedures to measure performance parameters under reference and stress conditions, producing data that supports the technical conclusions of the evaluation report.

Conformance and interoperability testing uses standardized protocol test suites to verify that devices and systems communicate correctly with equipment from other vendors. This is particularly critical for IEC 61850 substation devices and common information model based data exchanges between grid management systems.

Real-time simulation and hardware-in-the-loop testing are employed to evaluate controllers, protection devices, and power conversion equipment under simulated grid disturbances, faults, and islanding scenarios that cannot be safely reproduced on a physical network. Power hardware-in-the-loop methods further allow full-power equipment to be tested against dynamic grid models.

Field pilot verification supplements laboratory work by demonstrating performance, stability, and user value in a real operating environment over an extended observation period. Measured operational data from demonstration projects provides strong evidence for maturity and benefit conclusions.

Expert review and technology readiness level scoring are applied to qualitative dimensions. A panel of independent subject-matter experts reviews the technical documentation, test data, and intellectual property portfolio, scores maturity on a defined readiness scale, and issues consolidated opinions on novelty and advancement relative to comparable domestic and international achievements.

Benefit analysis methods, including cost-benefit comparison and life-cycle assessment, quantify the economic, energy-saving, and environmental value of the achievement, supporting conclusions on application prospects and promotion potential.

• Science and technology award applications: supplying objective test data and expert conclusions supporting nominations at provincial and national levels
• Technology transfer and licensing: establishing a credible technical baseline for negotiating licensing terms and transfer pricing
• Investment and financing due diligence: giving investors and financial institutions verified evidence of technology maturity and intellectual property strength
• Market access support: generating test evidence that supports subsequent product certification and grid procurement qualification
• Procurement and pilot deployment decisions: helping grid operators compare candidate technologies during vendor selection and demonstration planning

FAQ

What is the typical workflow of a smart grid achievement evaluation?

A standard workflow includes application and documentation submission, scope confirmation between the applicant and the evaluation body, testing and verification at accredited third-party laboratories, field or pilot verification where required, expert panel review, and issuance of the final evaluation report with defined conclusions.

What documentation is required for the evaluation?

Applicants generally submit the technical report, test records, user application reports, patent certificates and software copyrights, economic benefit documentation, and product specifications. Complete and traceable documentation significantly shortens the evaluation cycle.

How is an evaluation different from product certification?

Certification demonstrates that a specific product conforms to defined standards for market access, while achievement evaluation assesses the overall scientific and technological value of a research outcome, including novelty, maturity, benefit, and intellectual property position. Evaluation frequently incorporates certification-type testing as supporting evidence but reaches broader conclusions.
