1. industry benchmark, start the energy storage upgrade project
Distinguished Electrical Appliances is a leading enterprise in the domestic home appliance industry. It has been deeply involved in the industry for many years. With strong production strength, profound technical accumulation and good brand reputation, it occupies a pivotal position in the industry. As a large private enterprise, the company has multiple production bases, a huge production capacity and a professional team. Its brand influence is far-reaching, its products cover domestic and foreign markets, and it has won many industry heavyweight honors. It is a benchmark enterprise with both strength and reputation in the field of home appliances. Leading the high-quality development of the industry.
Anhui distinguished electrical appliance industrial park is located in the new station area of Hefei city, with a planned total construction area of about 240000 square meters. the first phase of Hefei production base covers an area of 210 mu, with a construction area of 150000 square meters. the overall scale is large, providing a solid spatial foundation for high-load continuous production. Relying on the industry’s leading technology research and development strength and perfect supply chain system, distinguished electrical appliances has built a core competitiveness that is difficult to replicate. Its production and operation have extremely high requirements for the stability, reliability and efficiency of energy supply. In the face of the “double carbon” goal led by the wave of energy transformation, distinguished electrical appliances layout energy storage field, together with Yaowei source to promote energy upgrading, highlighting the industry leader’s responsibility and innovation courage, for the traditional enterprise green transformation set a model.
combined with the core demand of high power load of distinguished electrical appliances, the 6.269MWh high-voltage container energy storage project jointly built by both parties innovatively adopts 10kV high-voltage direct connection access mode with container integrated design. from scheme customization to grid-connected operation, the whole process is efficiently promoted, keeps improving, and finally realizes high-quality landing.
2. to overcome the problem of high-pressure containers and realize the efficient landing of the project
the landing of this project has overcome multiple technical and practical problems in the whole process. with the double innovation of 10KV high-voltage direct connection and container integration, it breaks the bottleneck of the industry, realizes efficient, safe and rapid deployment, and perfectly meets the needs of enterprise production scenarios.
10KV high voltage direct connection is the core highlight of the project, but also the ultimate test of technical strength. Compared with the traditional energy storage scheme, the project innovation adopts the efficient topology structure of “battery cluster → PCS → 10KV boost → direct connection to the power grid”, which eliminates the multi-level conversion link, greatly reduces the line loss loss, significantly improves the system operation efficiency, and perfectly adapts to the high-voltage power grid access requirements. At the same time, in view of the safety risks in high-voltage scenarios, the project strictly abides by the construction specifications, is equipped with perfect five-prevention interlocking, multi-level safety protection and insulation monitoring systems, builds up safety defense lines layer by layer, realizes “zero potential safety hazard” grid connection, and can enjoy the three policy dividends of grid connection process simplification, auxiliary service compensation increase and capacity electricity price coverage, thus protecting long-term benefits.
the design of container prefabricated cabin effectively solves the pain points of limited site and long deployment period in the factory area. it highly integrates the whole modules such as battery system, PCS, booster device, intelligent fire fighting, liquid cooling management, etc. to maximize the space utilization rate and occupy only 1/3 of the site of the traditional energy storage scheme. The protection level of the cabin reaches IP54, which can resist the complex outdoor environment. The built-in high-efficiency liquid cooling system and 10-second intelligent fire fighting system can prevent safety risks in all directions. The mode of “factory manufacturing and on-site hoisting” is adopted to greatly shorten the construction period, realize “rapid production and rapid income”, and minimize the impact on the normal production of the enterprise.
from the customization of the preliminary plan to the final grid-connected operation, yaowei yuanchuang and distinguished electrical appliances are closely coordinated and promoted efficiently: the special team goes deep into the factory area to accurately measure the electricity demand, customizes the exclusive plan and reserves the second-phase expansion space; Set up a senior technical team to overcome the core problems such as high-voltage boost adaptation and cabin layout optimization, and simultaneously promote the whole process of equipment prefabrication, such as on-site hoisting and system debugging; strictly follow the national grid-connected specifications, successfully complete the whole process acceptance, and finally achieve a successful grid-connected, all indicators are better than industry standards.
3. project empowers enterprises and opens a new chapter of green development
The successful commissioning of this energy storage project has brought multiple values to distinguished electrical appliances and enabled enterprises to develop in an all-round way with high quality and green development. At the production level, the project can accurately take over the electricity load during peak hours, reduce the electricity bill by cutting peaks and filling valleys, and participate in the auxiliary services of the power grid to obtain additional income. It is expected to save more than one million yuan of electricity bill for the enterprise every year and effectively reduce the production and operation costs. At the development level, the project reserves the second expansion area in advance, which can quickly double the capacity and create a stepped energy upgrade path according to the enterprise capacity, provide stable energy guarantee for the long-term development of enterprises; at the brand level, as an important milestone in the energy upgrade of enterprises, the project demonstrates its responsibility to practice green development, and provides a scalable solution for the transformation of traditional enterprises in the industry with innovative energy storage models, Further enhance the brand influence and core competitiveness.
the successful grid connection of the 6.269MWh high-voltage container energy storage project of Yao Wei yuanchuang × distinguished electrical appliance is a triple superposition of technical strength, enterprise consensus and policy dividend. it is not only a concentrated display of Yao Wei yuanchuang’s hard core strength in the field of high-voltage energy storage, but also a vivid practice of distinguished electrical appliance’s active change and green transformation. In the future, the two sides will continue to work together to deepen the field of green energy, help achieve the goal of “double carbon”, and write a new chapter of win-win between industry benchmarking and new energy industry.
