Abstract
Electric power industry is the foundation of national economy and plays a key role in the development of human society. Traditional power industry is monopolized by industry and lacked of market efficiency. In recent years, it is seeking breakthroughs in the market-oriented reform. Although China’s electricity market reform has achieved some achievement, it is still lacked of market players, regional transactions, excessive data management, concentration and other defects. This paper puts forward higher requirements for the system design of power market transactions. The electrical power market is facing with the security and performance challenges, it is to improve the electrical power market transaction mode and to enhance transaction security, blockchain is a new decentralized framework and with a distributed computing paradigm, which integrates and innovates a variety of computer technologies, then it constructed a perfect competitive electricity market system. Using of different levels of multi auction trading model to integrate the province’s trading and inter provincial trading parts in one system. In the part of inter-province trading, it adopted the contract trading and bidding coexist pattern, the trade is carried out in each province Surplus-deficit electricity which based on the meet of the province’s demand basis. By using blockchain, it can conducted the intelligent contract and record the whole transaction information discretely, and provided the inquiry transaction channel to the users, so it can achieve the resource scheduling fairness and transaction information in security.
Highlights
Electrical power market reform has initiated in China since 2000, and it have made experiments in several provinces, it realized the separation of plant and network and achieved the competitive bidding construction of sell side market as in refers [1], the electricity market trading volume increased rapidly over the past two years, the total electricity consumption has gone up to 20% through market transactions in 2016 [2]
The State Grid is implementing power grid reform, it hopes to establish a competitive electricity market, but the present trade is still remained at the provincial level of internal market, it is weak in connections between regions, the trade between provinces electric resource trade is limited
The electricity market trade model proposed here can support the multi trade between the power generation and the purchasing power within the province and inter province range
Summary
Electrical power market reform has initiated in China since 2000, and it have made experiments in several provinces, it realized the separation of plant and network and achieved the competitive bidding construction of sell side market as in refers [1], the electricity market trading volume increased rapidly over the past two years, the total electricity consumption has gone up to 20% through market transactions in 2016 [2]. There are still some problems in the electricity market, for example, the power trading is mainly concentrated of the province market and the management mode is over centralization [3]. Its results in the existing electricity market is difficult to meet the market demand, on the other hand, the centralized data management leaded to the low data security and credibility, which prejudice the development of market integration and resource allocation [4]. In order to solve the above shortcomings, it is necessary to seek a decentralization platform technology to support large-scale regional electricity market transactions and more secure and reliable transaction data storage. Using the new emerging decentralization technology of blockchain, the problems in current power market transactions can be much better solved
