Multi-Energy Storage Coupled Thermal Power Frequency Modulation Tech

This document presents research and demonstration of multi-energy storage coupled thermal power frequency modulation technology by Xi'an Thermal Engineering Institute. It covers the background of fire storage frequency modulation technology, including traditional power system frequency adjustment methods and the impact of new energy development on grid scheduling. The document details a super-capacity energy storage frequency modulation demonstration project and introduces five new technology routes for fire storage and frequency modulation. It discusses the characteristics of new-generation coal power, such as fast regulation, low emissions, deep peak shaving, and wide load range. The frequency modulation ancillary service market mechanism and profit model are analyzed, highlighting the zero-sum game nature and performance-based revenue. National top-level policies from 2021 to 2025 supporting new energy storage development are reviewed. Regional differences in power grid structures and frequency regulation needs are noted. The pain point of independent frequency regulation technology for thermal power is identified as large adjustment inertia, making it difficult to meet multi-time scale regulation needs and leading to operational losses in frequency regulation markets.
