Energy Storage and Consumption of New Energy in Spot Market: Gansu Exploration
This document explores the integration and consumption of new energy in the spot market, focusing on Gansu Province's practices. Gansu Power Grid, a key hub for west-to-east power transmission, has over 100 million kW installed capacity, with new energy accounting for 64.2% and energy storage reaching 4.42 million kW. The province faces challenges from high renewable penetration and limited regulation resources. To address this, Gansu leverages its abundant high-energy loads (e.g., ferrous alloys, silicon carbide) and diverse energy storage technologies (lithium batteries, flow batteries, hydrogen, compressed air, molten salt). A key innovation is transforming rigid high-energy loads into flexible, adjustable resources through coordinated 'load-grid-source-storage' optimization control. This includes master-slave game decision mechanisms for multi-entity economic balance and multi-time scale rolling correction control. The approach enhances new energy consumption, supports green smelting, and won the 2024 First Prize of Gansu Provincial Scientific and Technological Progress Award. The document outlines the background, general idea, exploration practices, and benefits, aiming to scale these solutions for broader application.
