Description

Hydrogen fuel production and peak control power generation unit {To manufecture Hydrogen fuel and The method of controlling Hydrogen fuel at the peak of operating}

The present invention relates to an apparatus for producing hydrogen by electrolysis, and to a production and peak control power generation apparatus.

Hydrogen energy is the energy obtained by burning hydrogen, and this energy is clean because the raw material has no resource constraints with water, and even if it is burned, the product is water, and it is economical and efficient as it can transport pipe without disturbing natural circulation. It is characterized by being a means of energy storage. In addition to its use as a heat source, it is widely used for automobile fuels and aircraft fuels.

In particular, the present invention is used as a power generation means and an effective energy storage means, the invention for peak control at the peak power demand.

The term Demand Management (DSM) started in the United States in the 1970s and gradually spread to each country. Despite the theoretical economic feasibility and high potential contribution, the term DSM has not received much attention due to the promotion of the supply-side power supply plan of the previous utilities. Due to the increased security of the location, the enormous investment of fuels due to construction, the procurement of fuel, and the tightening of environmental regulations, it is difficult to secure timely supply facilities, and as part of the recent minimum cost planning, the optimization of supply-side and demand-side alternatives The proliferation of the concept of integrated resource planning, which seeks unions, has made demand management a critical consideration in power supply and demand planning, further highlighting the importance of demand management.

The ultimate goal of demand management is to rationalize power demand to reduce cost and stabilize power supply and demand, and to conserve national energy resources. In recent years, the environmental pollution problem caused by the use of fossil fuels is seriously emphasized as an environmentally friendly energy policy alternative.

Demand management can be divided into 'demand management by price' and 'demand management by non-price function'.

Demand management by price function is the most rational and efficient demand management method by price function, that is, electricity rate and subsidies. It is an indirect way of managing demand.

Seasonal and hourly differential fee system, summer vacation compensation period adjustment system, autonomous power saving support system, load transfer support system, midnight power bill system, direct load control system, emergency power saving system, etc.

As demand management by representative price function, the basic rate peak linkage system is for general, educational, industrial, and agricultural power customers. It's a program that encourages you to curb peak demand.

The monthly base rate is calculated based on the peak of the month of the meter reading and the peak of the summer (July to September) peaks in the previous twelve months.If the summer peak is shown once, the base rate is high for one year. You have to bear it.

Since its inception in January 1978, the system has contributed to the suppression of maximum demand.

Seasonal differential rate system is to induce the suppression of electric power demand concentrated in a specific season, especially summer cooling demand by applying electric power rate by distinguishing season with high power consumption and low season. This system was introduced in May 1990 and applied to business and industrial power. The rate is set at 10% more expensive than other seasons, reducing the maximum demand in summer.

The late night electricity (A) rate system has been introduced since 1985 to efficiently use electric power facilities by reducing the load during the daytime with high electricity consumption and by forming the load during the nighttime period with low electricity consumption. Applicable to customers using heat storage or heat storage facilities during the late night hours from 9am to 9am.

Even now, the power can be used only in the late night hours, and can be used for heating or cooling during the day time by making hot water or ice and storing it in the heat storage tank.

The late night electricity tariff system, unlike the late night electricity tariff system, which uses electricity only during the late night hours, is a system that uses electricity during the day, not the late night time together with the late night time. However, during the middle of the night, the unit price is higher than the general electricity rate.

This fee has been in effect since November 1988. When the late night power (A) is applied, it is applied only to the medium and large storage storage facilities, such as building storage facilities that are too large to be installed.

The vacation repair period adjustment support system is designed to suppress peaks and distribute electricity consumption by inducing summer vacation or facility repairs for general-use and industrial customers with a peak demand of 100kW or more during the expected period of peak demand in summer. A load management program first introduced in.

During the vacation rehabilitation period (which covers 2-3 weeks from mid-July to the 3rd week of August) agreed to by KEPCO and customers in advance, a vacation or facility maintenance for 2 or more consecutive days (excluding Saturdays and holidays) When the maximum demand power is reduced by more than 50% compared to the maximum demand power in the month, or when the reduction power is more than 3,000kW, the power industry infrastructure fund supports 650 won ± 10% per kW of power saved.

The autonomous power saving support system was introduced in 1995, which is a relatively recent load management program designed to save customers' electricity by reducing their own electricity consumption during peak hours of summer and contributes significantly to reducing peak summer load.

This system is intended for general-purpose, educational and industrial customers with a maximum power requirement of 100kW or more.In the period of 2 to 3 weeks from mid-July to the third week of August, agreed by KEPCO and customers. If the average power of the customer is reduced by more than 20% compared to the average power of 10 am to 12 o'clock, or more than 3,000 kW, the company will support 140 won ± 10% per kW of adjusted earnings.

In this case, it should be conducted more than 8 times except Saturdays and holidays, and it is regarded as one time every 30 minutes.

The main purpose of implementing this system is for business buildings with high summer cooling loads and for customers in the industrial sector that can adjust temporary loads. Therefore, the importance of this system is increasing day by day in view of the recent increase in cooling demand.

Direct load control support system With the development of electronic communication technology, the direct load control method for large customers such as industrial and general use has been implemented since May 2001. This system is to control customer's load remotely by communication if necessary to adjust power load adjustment amount through supply agreement with customer in advance. When the power supply and demand situation, if the DLC server transmits a control signal to the terminal device of the customer using the Internet network, the terminal device gives a control command to the control target load of the customer to directly control the load.

Direct load control applies to general purpose, educational and industrial customers with contract control power of 300 kW or more.

Emergency power saving system was introduced in December 2002 to prepare for emergency supply and demand caused by various reasons such as lack of energy. Customers and KEPCO can enter into an agreement in advance, and in the event of a supply-demand emergency, customers can reduce the use of power in order to stabilize power supply and demand. General purpose and industrial customers with a maximum power requirement of 300kW or more, which is applied when the power of reducing or reducing the average power by 20% or more is 1,000kW or more.

Demand management by non-price function is a demand management method that actively induces customer participation and strengthens demand management function by expanding equipment supply using rebate system. The reason for providing a rebate is to compensate for the market failure in the early stage of device distribution due to electric bill distortion and lack of consumer information.In the long run, the focus is on promoting the customer to voluntarily introduce highly efficient and economical devices. Should be implemented.

Current rebates include grants for installation of refrigeration cooling systems and subsidies for energy-saving high-efficiency lighting equipment and high-efficiency vending machines and high-efficiency inverters.

Representative examples include refrigerated cooling equipment, remote control air conditioners, high efficiency lighting equipment, high efficiency vending machines, high efficiency inverters, high efficiency transformers, heat storage cooling, water heaters, and the like.
