RESEARCH ON CORRELATIVITY AMONG AIR TEMPERATURE, MAXIMUM LOAD AND POWER CONSUMPTION IN SHANDONG POWER GRID

Zhaoguang Hu

Based on the data of load and power consumptionin Shandong power grid, the authors analyzed the influences of various meteorological factors on power load and powerconsumption by use of statistics method and scatter diagram, and drew the conclusion that the main influencing factor was airtemperature. On this basis a kind of software to analyze thecorrelativity among meteorological factor, load and powerconsumption was developed. The obtained features and regular patterns on the influences of air temperature on load and power consumption could offer useful reference information for thepersonnel in power supply and dispatching departments.

Research on consumption potential of uncertainty photovoltaic generation based on efficiency power plant

Yanan Zheng Zhaoguang Hu Quan Wen Baoguo Shan Han Li

As solar with the highest development potential, photovoltaic (PV) generation increases fast in installation and grid connection with continual mature and improvement of relevant technique. However, the inherent uncertainty of PV generation has direct influence on the stable operation and consumption potential of its connected system, and this has become one of the key problems relating to continuous development of power system. In order to study the consumption potential of uncertainty PV generation in the existing power system, this paper first analyzed the characteristics and regulation potential of different efficiency power plants. Then a consumption assessment system of uncertainty generation was developed, which considered the participation of efficiency power plants in system regulation together with the conventional power plants, the equipment control margin and the optimization layout of uncertainty generation. Finally, some effects on the consumption potential of PV generation are studied by simulating in the test system, which include the node voltage compensation, efficiency power plant participation, disperse connection and nearby consumption, and some ways for improving consumption was explored.

Simulation of Large Customer Price Response Under Time-of-Use Electricity Pricing Based on Multi-Agent System

Jiahai Yuan Jing Wang Zhaoguang Hu

The mechanism of customer TOU response is the key for success of time-of-use pricing. However different customers have different price response behavior and no simple analytic model is possible for it. Therefore multi-agents simulation is introduced. In simulation research TOU price response is taken as a decentralized decision process of all related customers, while power supply corporation can dynamically adjust its policy according to customer response. The paper discusses in details with the design principle and framework of the simulation system. In the system customer agent is implemented as responsive agent with its response rules built on fuzzy logic, utility agent is implemented as learning agent with classifier learning algorithm as its learning rules, and environment management module manages the interaction among them. Then the simulation flow is given and finally a case study based on a real power supply corporation is given and simulation results reported.

Fuzzy AHP and Its Application

ISAHP proceedings (1988)

Zhaoguang Hu

How to use fuzzy informationin hierarchical analysis is to be discussed in this paper..We use R -fuzzy sets instead of exact ratio.In order to reduce the calculation, the new concepts and operators are defined.We can see that the multiple expert's judges can be summarized in the R-fuzzy sets, and also it can reduce the calculation process.kpumerical example is given and the summary which compairs with previous researth 'is also made in the paper.

Study on the Architecture of National Electric Power Supply and Demand Simulation System

Zhaoguang Hu Xiandong Tan

It is significant to establish national electric power supply and demand simulation system. This paper aims at studying the architecture of the simulation system from three respects: software structure, database platform and system functional module. Firstly, in the case of software structure, the simulation system is designed to be based on the mixed pattern of B/S (browser/server) and C/S (client/server), and its structure is a multilayer distributed structure, including presentation layer, Web service layer, application service layer and data service layer; secondly, the database platform of the simulation system is classified into business database, achievement database and multimedia database; thirdly, concerning system functional module, the system consists of five modules: current situation analysis of power supply and demand, forecast of power supply and demand, early warning the imbalance of power supply and demand, important relationship of power supply and demand, and policy simulation.

Decision support system for thermal power plant siting (SDSS)

Wang Guang-sheng Zhaoguang Hu Pingyang Wang

On the basis of new technologies such as fuzzy sets, analytic hierarchy process and expert systems etc., a practical decision support system for thermal power plant siting (SDSS) has been set up and is presented in this paper. SDSS, as displayed on the PC screen, consists of ten parts: introduction, system maintenance, individual decision, clear database, consultation, auxiliary operation, multiple decision, sensitivity analysis, graph system and exit. SDSS can help decision makers to make individual decisions and multiple decisions on the site alternatives, in the preliminary feasibility study stage for thermal power plant siting, then it outputs the decision results and their certainty factors. SDSS not only can explain its reasoning process, decision results and rules in detail but also provide some expert conclusions in special fields for users. Guided by the domain experts SDSS can modify or enlarge its knowledge base easily. Through changing the weights of the criteria SDSS can do a sensitivity analysis on any site alternative if the users want. SDSS has good flexibility and can be used as a frame structure to form the expert systems in other fields. The man-machine interface in SDSS is clear and audio-visual, the decision results can be shown in all kinds of displays. SDSS can be applied to the other domains and the designing institutes throughout the country. Application of SDSS to the site selection of Wu Shashan, Ying Longshan, Qiang Jiao along the Zhe Jiang coast obtained a good result.< >
