Business Investment Analysis And Operation Optimization Research Of Electricity Company Under Mixed Reform

On March 15,2015,the Central Committee of the Communist Party of China and the State Council issued the "Several Opinions on Further Deepening the Reform of the Electricity System"(Zhongfa[2015]No.9),pointing out that the prices for the development of electricity and the sale of electricity are competitive links.Control the prices of natural monopoly links such as power transmission and distribution.On August 24,2015,the Central Committee of the Communist Party of China and the State Council issued the "Guiding Opinions on Deepening the Reform of State-owned Enterprises"(Zhongfa[2015]No.22),proposing to develop a mixed-ownership economy,promote the reform of state-owned enterprises by classification,and improve the state-owned assets supervision system Clear opinions.In the context of the "dual reform" of the power system and state-owned enterprises,grid companies need to explore mixed ownership reforms and their state-owned capital investment and operation development models,improve operational efficiency,promote the optimal allocation of capital,and enhance the vitality of state-owned enterprises.The paper takes state-owned power grid companies as the research object,and studies the selection of business investment areas,investment effectiveness analysis and operation optimization models under the mixed ownership reform.The main research content includes the following aspects:(1)Analyzed the relevant policies and ways of state-owned enterprise mixed reform.Starting from the three dimensions of the national level,local government level,and power grid companies,the relevant policies of mixed ownership reform of state-owned enterprises are sorted out.The classification and stratification of state-owned enterprise mixed reforms,and the ways in which various types of capital participate in mixed reforms are studied,and the basic process of mixed reforms of central enterprises is proposed.Aims to lay the foundation for further business investment analysis and operation model research of power grid companies(2)Constructed an economic evaluation model for power grid enterprises under mixed reform.Proposed mixed-reformation business types such as competitive power distribution business areas,integrated energy services,and micro-grids containing photovoltaics.Based on the SWOT model,it analyzes the opportunities and threats of the power grid companies developing mixed reform.Based on the economic analysis model,the economic evaluation model of the mixed-reform business of power grid enterprises is constructed.(3)An optimization model for the investment and operation of the microgrid business of grid enterprises has been constructed.Analyzed the feasibility of investment in photovoltaic location,electric vehicle charging,energy storage and other businesses.By analyzing the life cycle cost-benefit model of the microgrid and indicators such as net present value,internal rate of return,and investment payback period,the microgrid cost-benefit analysis model model was constructed.Taking into account the uncertainties of new energy sources such as wind power and photovoltaics,the CVaR method and robust stochastic optimization theory are introduced to construct a multi-scenario investment and operation optimization model for microgrid business.(4)Constructed an optimization model for the investment and operation of the integrated energy service business of power grid enterprises.Analyzed the market transaction business models for the integrated energy of cooling,heating and power,and constructed an optimization model for integrated energy operation of cooling,heating and power.Select typical demonstration projects to carry out case analysis,analyze the profitability of power grid companies investing in integrated energy service business under different businesses,and the comprehensive utilization of clean energy such as wind power and photovoltaic power generation.(5)Proposes an optimization model for the investment and operation of power grid enterprises’ competitive distribution and sales business.The business model of distribution and sale of electricity under the mixed reform was sorted out.With asset utilization as the investment optimization goal,establish an investment optimization model for incremental power distribution business that introduces distributed power sources.Based on electricity sales transaction and game analysis,construct a system dynamics model of power sales strategy of grid companies,and give corresponding load deviation adjustment strategies.(6)Constructed an evaluation model for the operation effectiveness of different mixed-reformation services for power grid enterprises.Established an evaluation index system for the mixed-reformation business of power grid enterprises,combined with the entropy weight method and the order relationship analysis method to give integrated weights to the indicators,and constructed the effectiveness evaluation model of the combined mixed-reform business.
