Energy storage applications can be divided into three major scenarios: power generation side,transmission and distribution side,and user side.These scenarios can further be categorized based on energy-based demand and power-based demand.Energy-based requirements,such as energy time shift,prioritize longer discharge times and do not have strict response time requirements.On the other hand,power-based requirements,like system frequency regulation,require fast response capabilities but shorter discharge times.It is important to analyze the specific needs in each scenario to identify the most suitable energy storage technology.

Starting with the power generation side,energy storage is used to meet various demand scenarios.These include energy time shift,capacity units,load tracking,system frequency regulation,reserve capacity,and renewable energy grid connection.Energy time shift involves charging the battery during low load periods and releasing the stored power during peak electric load periods.This is helpful in peak load shaving and valley filling.It is also used to store renewable energy and balance the grid connection over different periods.Capacity units,on the other hand,focus on reserving a certain amount of power generation capacity to meet peak load requirements.This helps improve the utilization rate and economic performance of thermal power units.

Yük takibi, yavaş yavaş değişen yükleri gerçek zamanlı olarak ayarlayan yardımcı bir hizmettir. Bu, esas olarak rampa yükleri için kullanılır ve geleneksel enerji ünitelerinin rampa hızını en aza indirir. Sistem frekansı regülasyonu, enerji üretiminin ve elektrikli ekipmanların güvenli ve verimli çalışmasını sağlamak için çok önemlidir. Geleneksel enerji kaynaklarının şebeke sevk talimatlarına yanıt verme konusunda sınırlamaları vardır, enerji depolama, özellikle elektrokimyasal enerji depolama, hızlı frekans modülasyon hızı sunar. Yedek kapasite, acil durumlarda güç kalitesini ve sistem istikrarını sağlayan aktif güç rezervini ifade eder. Yıllık çalışma frekansı rezerv kapasitesi uygulamaları için genellikle düşüktür. Son olarak, yenilenebilir enerji şebekesi bağlantısı, rüzgar ve güneş enerjisi gibi yenilenebilir enerji kaynaklarının aralıklı ve rastgele özelliklerinin ele alınmasını içerir. Bu, enerji zamanının kaydırılmasını, enerji üretim kapasitesinin sağlamlaştırılmasını ve çıktı yumuşatılmasını içerir.

Moving on to the transmission and distribution side,energy storage applications focus on alleviating congestion,delaying the expansion of equipment,and supporting reactive power.Alleviating transmission and distribution congestion involves storing untransmitted power during line congestion and discharging it when the load is lower than the line capacity.This helps balance the supply and demand and requires a discharge time of around an hour.Delaying the expansion of power transmission and distribution equipment relies on energy storage systems to improve the capabilities of the power grid without the need for new facilities.The operating frequency is lower compared to congestion alleviation.Reactive power support regulates transmission voltage by injecting or absorbing reactive power on transmission and distribution lines.This ensures grid stability and power quality.

Lastly,on the user side,energy storage applications focus on time-of-use electricity price management,capacity fee management,improving power quality,and enhancing power supply reliability.User time-of-use electricity price management adjusts power load based on the time-of-use electricity price system,while capacity fee management reduces maximum power consumption to reduce costs.Energy storage systems help users store energy during low power consumption periods and discharge it during peak periods.This helps reduce overall load and capacity costs.Improving power quality is achieved through smoothing voltage and frequency fluctuations,especially in distributed photovoltaic systems.Finally,energy storage improves power supply reliability by ensuring uninterrupted power supply during outages.

In conclusion,energy storage technology offers various application scenarios in the power generation side,transmission and distribution side,and user side.In each scenario,the specific needs must be analyzed to determine the most suitable energy storage technology.Whether it is energy time shift,capacity units,load tracking,system frequency regulation,reserve capacity,or renewable energy grid connection,energy storage plays a critical role in optimizing power system operations,improving power quality,and enhancing reliability.
