As the world grapples with the pressing need for sustainable energy solutions,the future of renewable energy has become a focal point for scientists,policymakers,and companies worldwide.Yet,despite the rapid advancements in technology and increased investments in renewable sources of energy like solar and wind,a critical issue looms – the capacity of power systems to adjust to burgeoning energy input from these renewable sources.By 2027,there is a potential silver lining; projected enhancements in the operational capacity of power systems could open doors to a more robust market environment and novel business models for various forms of adjustment resources.This development would serve as a backbone for managing an anticipated additional capacity of over 200 million kilowatts in new renewable energy sources each year.

In recent times,the European electricity market has been particularly illustrative of the challenges faced – particularly the curious phenomenon of negative electricity prices.This occurred last year,especially in Germany,where the first trading day in 2025 saw four hours of negative pricing due to an oversupply of renewable energy that the market simply couldn’t handle.Countries like the United Kingdom,France,and Spain have also experienced similar situations.Collectively,these occurrences paint a stark picture of the obstacles faced by energy suppliers and the limitations of current infrastructures to adapt seamlessly to intermittent renewable energy.In China,regions with operational electricity spot markets have begun to see negative pricing,amplifying the urgent sentiment that the integration of renewable energy must be approached with careful adjustments to the existing power infrastructure.

Comparing this to various traditional power systems,renewable energy sources can be likened to “recalcitrant children” – unpredictable and undisciplined,introducing randomness and volatility into the energy supply chain.Wind and sunlight aren’t always available when demand peaks,creating critical needs for systems that can effectively manage these fluctuations.The ability of an electricity system to adjust to the variability in power supply directly impacts its reliability; when renewable power dips or spikes,the system must be able to quickly recalibrate with other resources or storage solutions to maintain stability.

China,recognizing the significance of solidifying its power system’s adjustment capabilities,has been increasingly proactive in enhancing its flexibly regulated coal-based electricity production.By the close of the third quarter in 2024,the nation had achieved over 600 million kilowatts in flexible coal power,with inter-provincial resource allocation capabilities exceeding 300 million kilowatts.Additionally,the cumulative scale of pumped storage hydropower reached approximately 55.91 million kilowatts,along with newly constructed advanced storage systems.This collection of resources aims to reinforce the country's renewable energy development,offering a complementary framework necessary for accommodating substantial inputs of renewable energy into the grid.

Despite these advances,the current capacity for system adjustment still lags behind the rapid additions of renewable energy installations.With an average increase surpassing 200 million kilowatts annually and projections indicating a surge in system absorption pressures through the 14th Five-Year Plan,it is clear that the existing framework may buckle under intense demand.For instance,the national utilization rate for wind energy stood at 96.4% for the first ten months of 2024,reflecting a decrease from the previous year; similar trends were observed in solar energy,highlighting emerging difficulties in certain rapidly-growing regions.There remains a crucial need for optimized resource utilization and the refinement of pricing and market mechanisms to address these emerging challenges.

This situation makes it evident that strategic planning and precision in layout are critical.Tailored capacity planning serves as the foundational guideline for constructing effective adjustment capabilities,requiring local regions to develop acute plans based on actual conditions and energy production forecasts.This systematic approach acts as a work plan,calculating necessary adjustments in relation to projected renewable growth rates and usage targets,thereby maintaining equilibrium in power supply and ensuring reliable service.

While planning serves as a crucial first step,execution must be equally diligent.Irrespective of a sound plan,if the operational call of resources lacks coherence with system demands and technical safety,its potential will remain largely untapped.Presently,the mechanisms for resource application underutilize the existing assets,with some storage facilities remaining idle and unoperational.Therefore,by enhancing the classification and dispatching systems for adjustment resources,the Chinese electrical system can fully leverage its flexibility resources,optimizing their functionality while meeting demand effectively.

Finally,stimulating a robust market mechanism is indispensable in unlocking the potential of adjustment resources.The introduction of policies simplifying the peak and valley pricing systems,alongside initiatives that allow for the customization of auxiliary services,culminates in fostering an engaging environment for various types of adjustment resources.Such measures are projected to instill vibrancy within the market,ushering in an era where effective resource allocation thrives under strong incentives and structured motivation.

The expansion of adjustable capability coupled with an efficient resource deployment framework is of paramount importance for the evolution of a modern electricity system.As we confront the pressing deficiencies in power system adjustment,it is vital to adopt a steadfast approach akin to the determination seen in tightly nailed designs,implementing dedicated efforts to enhance capacity optimization initiatives.These measures will lay the groundwork for the substantial,high-quality growth of renewable energy in the years ahead,forming a critical support system for sustainability-oriented developments across global energy landscapes.
