"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 individual devices or vehicles that matters. An Energy Management System (EMS) that maximizes generation capacity and optimizes EV charging is essential to maximize the effects of decarbonization. Conventional EMSs are centralized monitoring and control systems similar to large servers that manage and control information and commands from each device collectively. As a result, the costs associated with implementation are significant, and every time devices are added or replaced, system modifications are necessary, leading to additional effort and costs. On the other hand, Daihen's EMS "Synergy Link" comes standard with palm-sized "modules" (small brains) in solar power-related devices such as power conditioners provided by Daihen, battery storage systems, and EV charging systems. Each device autonomously controls output values and charging amounts, always guiding them to the optimal state. Daihen provides one-stop support for various decarbonization initiatives.

• Substation equipment

A transformer that converts high-voltage electricity generated at power plants into electricity that can be used in homes and buildings. Generally, the lifespan of a transformer is said to be around 20 to 30 years, but to operate it for a long time and in a stable manner, it is important to carry out planned and proper maintenance. Daihen was founded in 1919 as "Osaka Transformer" and has developed numerous transformers to meet needs up to the present day.

■Maximize the use of electricity generated by solar power through packaging! Even when solar power generation is introduced, 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 peak in electricity demand caused by concentrated EV charging. The self-consumption package combines solar power generation equipment, storage batteries, EV charging systems, etc., all equipped with our unique control technology "Synergy Link." This allows for the 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 requests! When introducing the self-consumption package, we conduct a unique pre-simulation to estimate 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 enables us to propose the most suitable equipment based on your facility's situation and requests. ■Easy to introduce self-consumption solar power generation and expand equipment! By introducing the package, individual equipment selection and complex design become unnecessary, making it easy to expand or replace equipment and reduce costs associated with system modifications. This allows for flexible responses to future decarbonization efforts.

■ 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 electricity generated during active production for later use. In factories, for example, electricity can be stored on low-consumption holidays and shifted for use on weekdays, further minimizing waste. 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 a countermeasure against disasters such as typhoons and earthquakes, which have been increasing 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.
