Enterprise Risk Management (ERM) related to the sustained, stable and healthy development, it is a very important work. Comprehensive risk management point of view, a considerable number of enterprises is still relatively weak awareness of risk management, enterprise risk analysis and pre-control is not comprehensive, enterprise decision-making can not be fully understanding of the system to the enterprise in which the level of risk affect the strategic management and planning, there is an urgent need for a comprehensive risk management, the enterprise is a comprehensive medical examination. Grid enterprise is in a market-oriented business environment, internal and external corporate full of all kinds of risk factors, these risks losing control will bring great losses to the enterprise, research Grid Corporation faced a variety of operational risks, a respect for the power grid enterprises is a forward-looking topics run grid Corporation of health and sustainable development of great significance, on the other hand, the pilot and the implementation of the price ladder to do some theoretical explorations and research for the establishment of transmission and distribution separately.In this paper, at first the risk management theory development process are reviewed, the commonly used in electric power market of the risk assessment model combing and induction, this paper focuses on the modern risk management theory of overall risk management theory TRM, and risk management theory, the development trend of overall Enterprise Risk Management (ERM) theory. For electric power market in common use in the analysis method and model, the paper focuses on the partial moment measurement theory and its evaluation, based on the utility function of the risk measurement model, the analytic hierarchy process (ahp) theory and its evaluation.Power grid company’s risk identification is comprehensive, this article selects HN electric power company as an example, discusses the risk of all aspects of the enterprise management, and the influence of the power of the upstream industry coal industry are analyzed, from the current coal price fluctuation, this paper established the electric coal price fluctuation risk measure model, and analyses the electric coal price fluctuation of HN company profit influence, puts forward some Suggestions to face the price fluctuation risk precontrol method. Then the distribution of electricity price and time-of-use electricity price, electricity industry difference, bulk sale price risk identification and measurement, through the cost calculation established the cost analysis model, and then puts forward the prevention and control measures. This paper gives the pricing strategy, and how to through the change of electricity to power the adjustment methods for actual price risk management to provide a theoretical basis.Then on power transaction module on the risk identification, this paper analyzes the purchasing power risk of distribution, the average-variance risk optimization model, we study the HN electric power company inside and outside of the market for the risks of power distribution, this paper puts forward the minimum risk, income of the largest power purchase plan. Analysis the direct purchase of electricity customers bring risks, puts forward some Suggestions to face the direct purchase of electricity risk prevention and control strategy:For electric power marketing risk module on the risk identification, this paper analyzes the risk of line loss management, through the line loss decomposition, and gives the tecHNical line loss and management line loss risk prevention and control strategy; From the internal management and customer difference two aspects analyzes the electricity recovery risk, and puts forward the customer credit evaluation index system, a electric power customer classification management, reinforcing the enterprise internal accounting and management measures.HN provincial power grid investment risk from the perspective of income-risk analysis, breakeven analysis, sensitivity analysis of the HN Provincial Power Company "Eleventh Five-Year" grid investment results were evaluated and given according to the investment optimization modelgrid investment risk prevention and control strategies. UHV construction risk module into the the grid investment risk module unified research, the UHV will give HN provincial power company power purchase selection risk, after the study concluded that the efficiency of resource use, per kilometer transmission line loss of0.003%. coal calorific value14644k.1for the line, the more coal heat below the demarcation level, the less line loss, the UHV way transmission efficiency, the higher; coal Higher heat in boundaries of the level, the greater the line loss, the higher the efficiency with a the coal way to transport energy. Comparable fuel costs are calculated for different tce spread the cost economy of the critical distance, less than the critical distance, the UHV transmission program has more advantages in terms of cost, the critical distance outside the coal handling program comparable fuel cost advantage.Of energy-efficient scheduling risk identification, the change in the energy-efficient scheduling mode, scheduling Sort, in turn will cause the cost of security and optimization in three areas of risk. The macro risk prevention and control of proposed tariff adjustment, power grid security. Micro angle from scheduling order bits, compensation mechanisms and scheduling monitoring risk prevention and control; grid operators risk identification, the grid safety analysis model, for the HN characteristics provincial power grid, given from a human factors natural factors, equipment factors, such as power grid three aspects of prevention and control strategies.Last comprehensive study of each module, build the the grid enterprise-wide risk index system, using the analytic hierarchy process evaluation and summing up enterprises’overall level of risk faced by management to establish an efficient, sound risk management system. |
