"I introduced solar power generation, but the results are not great." "I introduced EVs for our sales vehicles, but instead, electricity costs have skyrocketed." Are you facing such concerns? When operating renewable energy generation and EVs, it's not just the performance of the equipment and vehicles themselves that matters. An Energy Management System (EMS) that maximizes generation capacity and optimizes EV charging is essential to maximize the effects of decarbonization. Traditional EMSs are centralized monitoring and control systems similar to large servers, managing and controlling information and commands from each piece of equipment collectively. As a result, the costs associated with implementation are high, and system modifications are necessary each time equipment is added or replaced, leading to increased effort and costs. On the other hand, Daihen's EMS "Synergy Link" comes standard with palm-sized "modules" (small brains) in solar power-related equipment such as power conditioners provided by Daihen, battery storage systems, and EV charging systems. Each piece of equipment autonomously controls output values and charging amounts, always leading to the optimal state. Daihen provides one-stop support for various decarbonization initiatives.

One of the major challenges in management is cost, particularly electricity fees. One effective method for reducing these costs is "peak cutting." Daihen has a unique energy management system that easily enables peak cutting, unlike any other. This document (PDF) clearly explains what peak cutting is, how it differs from a similar method called "peak shifting," and the specific benefits of its implementation. ---Table of Contents--------------------------------------------------------------------------------------------- 1.

The high-voltage electricity generated at power plants is converted into usable voltages of 100V or 200V for households through transformers installed on utility poles. However, facilities such as buildings and factories that use a large amount of electricity at once need to receive electricity at high voltage without conversion and require "substation equipment" to change the voltage within the facility. Daihen provides various substation equipment tailored to the usage environment. This document (PDF) clearly explains what substation equipment is, along with its roles and components. ---Table of Contents----------------------------------------------------------------------------------- 1.

■Maximize the use of electricity generated by solar power through packaging! Even with the introduction of solar power generation, there are often cases where the expected reduction in CO2 emissions does not materialize due to the generation of surplus electricity (waste) from not using storage batteries and the power peaks caused by concentrated EV charging. The self-consumption package combines solar power generation equipment, storage batteries, and EV charging systems, all equipped with our unique control technology "Synergy Link." This enables full utilization of solar power generation electricity and can increase CO2 reduction by up to 50%*. *Compared to typical usage conditions without EMS. ■Optimal proposals tailored to your facility's situation and requirements! When introducing the self-consumption package, we conduct a unique pre-simulation that estimates the amount of electricity that can be generated by solar power and the capacity of storage batteries that can effectively utilize surplus electricity generated on holidays. This allows us to propose the most suitable equipment based on your facility's situation and requirements. ■Easy to introduce and expand self-consumption solar power generation! By introducing the package, there is no need for individual equipment selection or complex design, making it easy to expand or replace equipment and reduce costs associated with system modifications. This also allows for flexible responses to future decarbonization efforts.

• Power storage device

■ Store excess electricity and make effective use of it! Power generation relying on natural energy sources such as solar and wind is easily affected by sunlight and wind conditions, so it is effective to store and use electricity generated during active production. In factories, for example, storing electricity on low-consumption holidays and shifting it to weekdays allows for even more efficient use. In large-scale renewable energy power plants, it also plays a role in compensating for output fluctuations during grid interconnection. ■ Can be used as an "emergency power source" for disaster (BCP) measures! As disaster measures against the increasing number of typhoons and earthquakes in recent years, solar power generation and battery systems can be utilized as "emergency power sources" during power outages, supplying various critical loads (such as electrical equipment). ■ Can be utilized as grid-connected storage batteries! With the expansion of renewable energy, strengthening "supply-demand adjustment capabilities" has become a challenge, and the government has announced strong support for the installation of large-capacity storage batteries. Daihen is promoting proposals for the installation of grid-connected storage batteries at battery storage facilities, leveraging its unique technology "Synergy Link," which enables optimal charge and discharge control.
