A Study On Retail Electrictity Market

It has become a common practice for the countries, which have carried out electric power industry reformation, that giving end-user right to freely choose energy provider. Due to its very beginning in China, the retail electricity market is still a new task to be studied. This paper focuses on three topics to discuss its great significance, that is, the influence on home load management, the new requirement for automation systems and the boost on Distributed Generation (DG) resulting from electric power retail competition. The Home Automation System (HAS), energy provider's consumer service center automation system and all kinds of DG technologies will make great progress in the retail electricity market. The retail electricity market will eventually become a true commodity market full of fair competition due to energy producer, energy provider and end-user's actively participation.This paper outlines main contents of retail electricity market to be studied at first. Then, the participants' different roles in the market environment are paid more attention. The negotiation contents in the retail contract are summarized through analyzing the process of electricity retail wheeling and the sale power price composing. The importance of electric power marketing is discussed and the general strategy of designing favorable price is put forward. As a result, the concept of retail electricity market is built up completely.End-users will response actively to the energy provider's flexible price strategy. So this paper makes a study on HAS' functions and configuration scheme. The Demand Side Management (DSM) will embody much high value due to the HAS and the HAS will bring into important play in the retail electricity market.Power grid automation system needs to be updated in the new environment. This paper explores their new characteristics of Metering and Reading System, Load Management System and Distribution Automation System, brings forwards energy provider's consumer service center automation system's functions and configuration scheme, analyzes their correlation among automation systems in the market. The energy provider automation system will play a very important role on the normal operation of retail electricity market.Retail electricity market brings vitality for the development of all kinds of DG. DG will do much impact on the control, operation, planning of distribution systems. This paper introduces their newly technological development such as wind generation, solar cell, fuel cell and micro-turbine. Further more, some distributed energy systems with DG are explored and a real case of that is studied. It can be concluded that the distributed energy system with DG has enhanced much its reliability.
