Research On Power Quality Market And Several Basic Academic Problems

With the electricity industry's deregulation, the management of Power Quality (PQ) suffers more heavily pressure from economy and social equity. Based on the modern quality management, value rules, external cost theory and environment economics, this thesis proposes the concept of electromagnetic pollution control and the idea of making PQ service marketable, summarizes the kernel idea of power quality market (PQM), generalizes its definition integrallty, establishes the PQM theory framework, explains the inherent relations of its contents, and summarizes the basic researching methods of PQM theory. Based on the operation and trading characteristics of PQM, this thesis proposes the basic framework and functions of PQM system, and explains it from six primary market elements in detail. Then the running mechanism of PQM is explained, including charging for any pollution policy, emission permit regulation, Emission Right (ER) trading method, PQ service actualizing modes and so on. Establishment and functions of PQ supervising department are also illustrated, and some primary technical and non-technical factors that affect the operation of PQM are proposed. For optimal gross ER control and initial allocation of ER, a method for quantifying and standardizing for electromagnetic pollution current is proposed, the behavior of all members in point of common connection to strive for ER and good PQ is analyzed applying game theory, and their strategy sets in game are defined. The uniform-price sealed auction method for ER initial allocation is proposed. Then optimal pollution gross that can satisfy Maximizing Benefit and Bayesian Nash equilibrium of initial allocation that can satisfy Pareto Optimality are worked out. To make PQ service marketable, reasonable pricing method is necessary, the essential is pricing electricity by quality. This thesis introduces the risk management method into PQM, and proposes a new pricing method for power quality service, that is to add PQ insurance to basic electric energy price, also an improved method for it is proposed. Prices of basic electric energy and PQ-service can be separated naturally, value of PQ service is made explicit, and PQ accidents can be compensated rationally. They can actualize pricing electricity by quality, and improve electric energy supply with multi-quality. PQ service market needs advanced PQ evaluation methods. This thesis proposes a new PQ evaluation method and an electricity pricing method considering PQ based on customers'requirements and process capability indices. They overcome several defects of traditional ones. They can help customers to evaluate PQ quantitatively and to choose their optimum power provider; they also can direct electric utilities'production and help them to analyze the economy of PQ investment. Finally, several basic problems of PQ investment are researched primarily.
