This research tried to develop an ESS electricity trading system linked with blockchain for energy participation consumers. For the purpose of publishing renewable energy ESS power amount and demand information, we will build a smart contract system on the blockchain DB, utilize the blockchain DB data of energy prosumers and consumers, and expand the power trading market flexibly. to provide realistic solutions. Therefore, the main contents of the development of the ESS power trading system linked to the blockchain are cloud-based web construction for ESS management, coin issuance and exchange registration for activating the blockchain, and to reflect the blockchain technology, building a blockchain database for collecting and supplying ESS-based production demand data, selecting a blockchain-based platform and building a foundation, and creating a smart contract, etc.

As the environment of power systems changes, the demand and necessity for new electrical energy market are increasing. Especially, efforts to increase the efficiency of electric energy use by using demand response programs are being studied constantly in advanced countries and it is operated as a real market. This paper presents a study on the baseline load estimation required in the new power market, such as demand response, P2P electricity trading etc. The proposed method estimates the baeline load through analysis of the load pattern and verifies the effectiveness of the proposed method using actual data.

This article studies certain standards which have been developed for exchanging information about business and trading transactions, both nationally and internationally. In this context standards means standardised ways of representing trade information and standardised procedures for communicating it in computer-based environments. Early in the 1960s, the United Nations UN/ECE working party was formed. The purpose of the this organization was to simplify and standardize trade document. This organization eventually evolved into what is currently known as EDIFACT, the international EDI standards organization. EDIFACT is the basis for agreement on a common structure for documents such as those used for trading(e.g., orders, invoices), so that they can be interchanged electronically between computer systems. The standard was ratified in 1987 and has already been adopted by many EDI users for the earlier European and American standards for trading data interchange called UN/TDl and ANSI Xl2 respectively.

The purpose of this article is to study on the electronic bill of lading in the electronic trade era. The term 'electronic trade' means all or part of any such trade as implemented by means of apparatus having the information processing capability, such as a computer, and networks of information and communications. The introduction of an electronic bill of lading has long been considered essential by the members of the international trading community as a key means of reducing its costly reliance on paper.

Since July 7 mutual declaration in 1988 which is a landmark for South-North Korean relations, Inter-Korean Trade has been set out. During the period, the Inter-Korean Trade has been ups and downs depending on the Inter-Korean relations and economic situation of both countries. South Korea became one of the major three trading countries of North Korea's trading partners in 2000, when the sum of annual trade volume reached the record 425million US dollars. A rapidly increasing number of countries including North Korea are developing national policies and strategies to promote the digital economy, recognizing the potential benefits of e-business as an engine of growth and development. However, the trade structure of South-North Korea remains very simple in terms of its contents. Furthermore trade procedure many limitations especially electronic commerce in North Korea has many obstacles to working properly. The information in Inter-Korean trade cannot be shared in common. South Korean firms have suffered repeatedly trial and error and excessive competition took place among South Korean firms. Institutional inertia related to mutual trade, political and military Impacts on Inter-Korean economic relations, abnormal industrial structure of North Korea and insufficiency of SOC could be mentioned as major problems in Inter-Korean trade as well. Several measures should be taken in order to cope with those problems. First of all, South Korean government should provide valuable information to business firms about North Korean economy and business environments. It is suggested that forums related to inter-Korean trade hold in regular base between South and North Koreas and establish the system of business information sharing. Second, the government should improve various laws and regulations to respond to the realistic needs of inter-Korean trade. That is, detailed measures should be taken to guarantee investment in electronic commerce. Third, it is desirable to start with the mutual agreement between South and North Korea.

Because the international trading community has witnessed a number of significant technical and commercial changes, documentary credit practices will quite clearly need to be updated to meet both the business and technical demands of the latest commercial and technical developments in international trade. The potential for developing "paperless credit" should, therefore, be examined. TradeCard is a B2B(business-to-business) e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet and objective of TradeCard is to provide a secure, reliable cost-effective and user-friendly solution for conducting and settling international trade transactions. This paper analyzes the reviews of TradeCard by Electronic Message and the various problems which come to application of TradeCard, with particular attention to existing international frameworks for Payment systems based on Documentary Credit.ry Credit.

In this paper, the energy transaction system was optimized by applying a resource allocation algorithm and deep reinforcement learning in the distributed power system. The power demand and supply environment were predicted by deep reinforcement learning. We propose a system that pursues common interests in power trading and increases the efficiency of long-term power transactions in the paradigm shift from conventional centralized to distributed power systems in the power trading system. For a realistic energy simulation model and environment, we construct the energy market by learning weather and monthly patterns adding Gaussian noise. In simulation results, we confirm that the proposed power trading systems are cooperative with each other, seek common interests, and increase profits in the prolonged energy transaction.
