| With the development of low-carbon economy and the accelerate of western development strategy, China’s western region has an unprecedented opportunity in the field of energy construction. The investors like major state-owned power generation groups and even private capital group have this as an opportunity to enter the energy construction of Gansu, Inner Mongolia and other western provinces. And launching a number of projects at the same time becomes the norm. This situation proposes a new test for enterprise’s multi-project management capabilities.Project portfolio management philosophy is an important method and means to solve enterprise’s multi-project management. However, currently the researches on energy construction projects’s multi-project management are still lacking in domestic. The trail in management methods becomes the biggest bottleneck that restricts the development of enterprises. For investors, how to ensure that the selected projects are in line with their strategic objectives, how to combine and optimize the projects that have been selected, how to ensure the stable operation of project portfolio management, how to control portfolio risk, and how to achieve the communication of a large project portfolio management are all the problems in management. This study will focus on and solve these problems.Starting from the actual situation of the current energy construction projects in Chinese western region, this paper proposes the idea of the portfolio management of energy construction project network at the base of a large number of researches about project portfolio management. Focused on early decision-making and implementation management, the two major parts of project management, this paper discusses the flow of energy project portfolio decision from the decision-making process, the decision-making model, resource optimization respectively, and proposes objective control method of project portfolio decision based on the the WBS.Firstly, this paper combs for grid portfolio management related methods and theories. Focused on early decision-making and implementation management, the two major parts of project management, this paper discusses the flow of energy project portfolio decision from the decision-making process, the decision-making model, resource optimization respectively, and proposes objective control method of project portfolio decision based on the construction five goals, project grid portfolio management WBS and project portfolio risk target control the overall process. It combines with the characteristics of energy power projects and project management knowledge, and discusses the grid portfolio decision model and project portfolio preferred selection and evaluation method. Based on the theory of constraints, critical chain theory and the time buffer theory, it proposes resource optimal allocation and scheduling approach. By project portfolio selection and evaluation it is preferable to establish a network of energy projects portfolio decision model.Then, this paper sets up the project network portfolio management system, building vertical and horizontal network. Vertical contact is the targets WBS (Work Breakdown Structure) based on the cascade targets of Huadian Mongolia energy (strategic level→management level→implementation level).The vertical contact decomposes the high-level goals of investment entities gradually extend to the low-level goals. And it discusses in detail the key points of different levels in network management, as well as the relevant methods adapt to different levels. Three levels of portfolio management each have their different focus and approach to portfolio management. The strategic level focuses on strategic. The management level emphasis on preference. The implementation level emphasis management during the project process, such as resource scheduling optimization. The horizontal contact is the contact among various project goals, different projects and project sets based on the project portfolio management of Huadian Mongolia Energy.Furthermore, in order to protect the operation of energy construction project grid portfolio management system, this paper discusses the management system and operational mechanism of the portfolio management system further. Firstly, it builds the project portfolio management organization and analyzes the main responsibilities of various departments, including the responsibilities analysis and design of project network portfolio’s organization structure. And then based on the characteristics of the portfolio grid management the process is divided into different stages, so as project grid portfolio management mode analysis and process design. As well as the design of project network portfolio management operation safeguard mechanism which covers the coordination mechanisms, risk warning mechanism and the dynamic performance evaluation mechanism.To apply the grid portfolio management mode in practical projects, this paper designs energy construction projects grid portfolio management information platform on the basis of theoretical studies. Through the platform we hope to achieve the automation management of projects process, to improve multi-projects management efficiency and enhance projects execution. The platform includes the design of system’s overall structure, data warehouse design and platform features modular design. Firstly, the overall structure and network architecture of energy construction project grid portfolio management information platform are designed. It applies advanced database technology to analyze and control all aspects of the project portfolio management. This provides strong support for project organization to hold and manage project portfolio, analyze the overall structure and function of the system. Secondly, business intelligence design is presented to introduce the system’s database. Then, the system platform function modules, operation processes and the features of system platform are introduced, in order to achieve the information management and portfolio management of energy construction projects grid portfolio management.Eventually, this paper takes Huadian Mongolia company’s energy construction projects for example to carry out the case study. First of all, Mongolia Autonomous Region’s energy reserve condition and energy consumption status are analyzed to show the Mongolia Autonomous Region’s advantage to develop new energy projects. Furthermore, this paper takes Huadian Mongolia wind and solar power demonstration project as an example, to indicate the implementation process of the enterprise’s projects portfolio. Combined with the actual situation of Mongolia Autonomous Region and energy power projects to be developed, the projects portfolio optimization methods in management level and implementation level are elaborated. Finally, the resource scheduling management method in implementation level is introduced. Ultimately, strategic level achieves the Group’s strategic coherence, the management level achieves the project optimization, the implementation level achieves project resource scheduling optimization, full revealing the application situation of energy power construction projects grid portfolio management system in the actual projects. |
