More and more deep integrated resource planning methods and demand side management (DSM) technologies have been studied and applied in China. Using technological and economic means of DSM, exploiting energy-saving potentialities from demand side, balancing load, easing contradictions of power structure, improving energy utilization rate, etc. have been important tasks in electric power enterprises. Based on this background, the paper designed and developed resources investigation and evaluation system of electric power DSM, which could investigate electricity resources of DSM of China, and implement energy-saving potential evaluation and energy efficiency analysis. From aspects of technology, economy, management, etc. suggestions were proposed for DSM, trying to be more rational and effective to allocate and use electricity resources, seeking satisfaction of power demands to the greatest degree, thus promote sustainable development of electric power enterprises effectively.

Chinese heating method has gradually shifted from small fragments to centralized regional heating. This heating method has achieved obvious energy-saving benefits. The article establishes an economic model of the energy utilization rate of the central heating system and installs the system exergy balance equation at the same time. The simulation found that the energy utilization coefficient of the heating system is high and has a high energy-saving potential. The effect of energy utilization is poor, and it has great potential for energy saving.

Integrated Resource Planning

Traditionally, the method used in the electricity generation expansion planning has concentrated only on the supply-side options to identify the sequence of generation additions meet the forecasted demand at a minimum cost. Electricity generation expansion planning with both supply- and demand-side options, commonly known as integrated resource planning are also being used in some developed countries. With growing environmental concerns, especially the emission of air-pollutants from the power generation, demand-side management and clean and efficient generation technology options in the power sector development are getting increasing attention. In this paper, we compare the traditional planning approach with integrated resource planning. We also analyze the implications of CO2 reduction targets for the power sector development in the framework of supply side planning by including clean supply-side technologies as candidate plants. During the planning horizon, generation capacity of 365 MW and a cumulative electricity generation or 61,681 GWh would be avoided through the use of efficient demand-side technologies compared to the business-as-usual (BAU) case. When the clean supply-side options considered in the least-cost planning process, three units of 100-MW biomass-based plants are selected. The long run average cost of generation is found to increase by 0.32, 0.65 and 1.61% at the level of CO2 emission reduction target of 5, 10, and 20%, respectively.

Integrated Resource Strategic Planning (IRSP) is an extension of Integrated Resource Planning (IRP) at the national level for power planning. It provides a new theoretical foundation for the implementation of demand-side management (DSM) in the deregulated conditions. In this paper, IRSP model for power planning is proposed. In the model, both supply-side and demand-side resources as efficient power plant (EPP) are considered in the optimization process. A case study for the power planning in the United States is presented in the paper. The results indicate that, comparing with traditional planning the IRSP model can not only achieve the minimum total costs, but also reduce the supply-side capacity installation and the related pollution emissions.

From the view point of efficiency, the energy consumption coefficient was used as the energy utilization evaluation index in a water supply pumping system, and through the comparative analysis between the energy consumption coefficient and the pump efficiency, the past pump efficiency that was used as the economic index in the system could not completely and scientifically reflect the energy utilization rate of the system, while the energy consumption coefficient could intuitively reflect conveying unit volume of liquid consumption in a water supply pumping system. Based on the theory of energy consumption coefficient, the comprehensive analysis of different energy saving methods, energy saving space estimation, and average energy consumption coefficient calculation under variable conditions of the system in a water supply pumping system can give a specific guidance scheme of energy saving to the system, and it has a guidance and reference significance to the energy saving reform in the water supply pumping system.
