1～2月，我国电力设备制造业运行依然较为疲软：受国内经济增长势头趋缓影响，电力设备制造企业投资动力不足，行业固定资产投资增速较上年同期下降2.24个百分点；行业市场竞争依然激烈，大部分产品价格上升乏力，在中国机械工业联合会统计的电力设备制造业22个小类行业中，价格指数低于100的行业有18个，高于100的仅有4个。与此同时，大部分发电设备产量受上年同期基数较低影响，实现了较快增长，成为前两个月行业运行中难得的亮点。预计2014年1季度，电力设备制造业大部分主要产品产量将实现增长，行业出口形势将有所改善，但主要产品价格仍将低位徘徊，行业投资依然增长乏力。

There is increased recognition that geothermal energy resources are more widespread than previously thought, with potential for providing a significant amount of sustainable clean energy worldwide. Recent advances in drilling, completion, and production technology from the oil and gas industry can now be applied to unlock vast new geothermal resources, with some estimates for potential electricity generation from geothermal energy now on the order of 2 million megawatts. Terralog USA, in collaboration with the University of California, Irvine (UCI), are currently investigating advanced design concepts for paired horizontal well recirculation systems, optimally configured for geothermal energy recovery in permeable sedimentary and crystalline formations of varying structure and material properties. This two-year research project, funded by the US Department of Energy, includes combined efforts for: 1) Resource characterization; 2) Small and large scale laboratory investigations; 3) Numerical simulation at both the laboratory and field scale; and 4) Engineering feasibility studies and economic evaluations.

This paper shows by means of simulation the existing frequency control is insufficient when large wind power generation is installed. This paper proposes a measure for the frequency control. A power system of 5,000MW capacity with governor free control and load frequency control is assumed for the study, and a wind power generation of 500MW capacity is assumed. A battery energy storage system is added for frequency control in the power system. Frequency control functions of the battery energy storage system are studied and a suitable control is proposed which coordinates with conventional frequency controllers. This paper proposes also minimum capacity of the battery energy storage system.

Many binary-cycle geothermal plants use air as the heat rejection medium. Usually this is accomplished by using an air-cooled condenser (ACC) system to condense the vapor of the working fluid in the cycle. Many air-cooled plants suffer a loss of production capacity of up to 50during times of high ambient temperatures. Use of limited amounts of water to supplement the performance of ACCs is investigated. Deluge cooling is found to be one of the least-cost options. Limiting the use of water in such an application to less than one thousand operating hours per year can boost plant output during critical high-demand periods while minimizing water use in binary-cycle geothermal power plants.

Thermo-economic model has been built and validated for prediction of project economics of Enhanced Geothermal Projects. The thermo-economic model calculates and iteratively optimizes the LCOE (levelized cost of electricity) for a prospective EGS (Enhanced Geothermal) site. It takes into account the local subsurface temperature gradient, the cost of drilling and reservoir creation, stimulation and power plant configuration. It calculates and optimizes the power plant configuration vs. well depth. Thus outputs from the model include optimal well depth and power plant configuration for the lowest LCOE. The main focus of this final report was to experimentally validate the thermodynamic properties that formed the basis of the thermo-economic model built in Phase 2, and thus build confidence that the predictions of the model could be used reliably for process downselection and preliminary design at a given set of geothermal (and/or waste heat) boundary conditions.

Because most sedimentary basins have been explored for oil and gas, well logs, temperatures at depth, and reservoir properties such as depth to basement and formation thickness are well known. The availability of this data reduces exploration risk and allows development of geologic exploration models for each basin. This study estimates the magnitude of recoverable geothermal energy from 15 major known U.S. sedimentary basins and ranks these basins relative to their potential. The total available thermal resource for each basin was estimated using the volumetric heat-in-place method originally proposed by (Muffler, 1979). A qualitative recovery factor was determined for each basin based on data on flow volume, hydrothermal recharge, and vertical and horizontal permeability. Total sedimentary thickness maps, stratigraphic columns, cross sections, and temperature gradient information was gathered for each basin from published articles, USGS reports, and state geological survey reports. When published data were insufficient, thermal gradients and reservoir properties were derived from oil and gas well logs obtained on oil and gas commission databases. Basin stratigraphy, structural history, and groundwater circulation patterns were studied in order to develop a model that estimates resource size, temperature distribution, and a probable quantitative recovery factor.

A smart water network is an integrated set of products, systems, and solutions that help water utilities to monitor and diagnose problems related to water distribution networks. Smart water networks can help in leak detection, pressure management, network operation, and water quality monitoring. It can also reduce the overall capital expenditure of the water utilities by providing real-time data based on the water consumption and customer meter readings.
