Modeling,evaluation, and optimization of gas-power and energy supply scenarios

Recently, renewable energy sources such as wind power and photovoltaic (PV) are receiving a wide acceptance because they are inexhaustible and nonpolluting. Renewable energy sources are intermittent ones because of climate changes in wind speed and solar irradiance. Due to the continuous demand growth and the necessity for efficient and reliable electricity supply, there is a real need to increase the penetration of gas technologies in power grids. The Canadian government and stakeholders are looking for ways to increase the reliability and sustainability of power grid, and gas-power technologies may provide a solution. This paper explores the integration of gas and renewable generation technologies to provide a qualified, reliable, and environmentally friendly power system while satisfying regional electricity demands and reducing generation cost. Scenarios are evaluated using four key performance indicators (KPIs), economic, power quality, reliability, and environmental friendliness. Various scenarios outcomes are compared based on the defined performance indices. The proposed scenario analysis tool has three components, the geographic information system (GIS) for recording transmission and distribution lines and generation sites, the energy semantic network (ESN) knowledgebase to store information, and an algorithm created in Matlab/Simulink for evaluating scenarios. To interact with the scenario analysis tool, a graphical user interface (GUI) is used where users can define the desired geographic area, desired generation percentage via gas technology, and system parameters. To evaluate the effectiveness of the proposed method, the regional zone of the province of Ontario and Toronto are used as case studies.     

Modeling and application of marketing and distribution data based on graph computing

Integrating marketing and distribution businesses is crucial for improving the coordination of equipment and the efficient management of multi-energy systems. New energy sources are continuously being connected to distribution grids; this, however, increases the complexity of the information structure of marketing and distribution businesses. The existing unified data model and the coordinated application of marketing and distribution suffer from various drawbacks. As a solution, this paper presents a data model of “one graph of marketing and distribution” and a framework for graph computing, by analyzing the current trends of business and data in the marketing and distribution fields and using graph data theory. Specifically, this work aims to determine the correlation between distribution transformers and marketing users, which is crucial for elucidating the connection between marketing and distribution. In this manner, a novel identification algorithm is proposed based on the collected data for marketing and distribution. Lastly, a forecasting application is developed based on the proposed algorithm to realize the coordinated prediction and consumption of distributed photovoltaic power generation and distribution loads. Furthermore, an operation and maintenance (O&M) knowledge graph reasoning application is developed to improve the intelligent O&M ability of marketing and distribution equipment.     

Powerful planning tools

Distributed power generation offers a solution to the limitations in the capacity of distributed systems and, at the same time, improves the reliability of the overall power system by increasing its generation capacity reserves. The planning process to integrate dispersed generation in power networks must take into account multiple factors such as the existing resources, the technology used in the generator, economic costs, and the environmental impact. Geographic information systems (GIS), software technologies developed for spatial data analysis, are suitable tools for solving these problems, and they allow the simultaneous evaluation of key technical, economic and environmental factors. The development of new techniques under the GIS platforms has increased the capabilities of GIS, allowing the systems to adapt to optimal DG planning studies. Using adequate software under the GIS platform, users can obtain useful information on the economic or technical viability of any distributed power generation facility. Governments, environmental agencies, utilities, private investors, financial corporations, and local authorities can become users of these tools and active players in the field of distributed power generation planning.

从标准看智能电网的发展

目前世界各国在什么是智能电网、如何推进智能电网的发展等方面并没有达成一致意见。美国设想的未来电力系统是一个完全自动化的电力传输网络,能够保证从电厂到终端用户整个输配电过程中所有节点之间的信息和电能的双向流动。欧洲智能电网技术平台的目标是提高输配电系统的效率、安全性和可靠性,消除大规模集成配网与可再生能源的障碍。日本将主要以大规模开发太阳能等新能源、确保电网系统稳定作为智能电网建设的主要思路。结合中国的实际情况,我国智能电网业务框架应包含发电、输变电、配电、用户、运行、服务提供者、电力市场及统一信息平台等8个领域。现有标准与智能电网之间存在差距,主要体现在需求响应和电力市场、广域状态测量、电力存储、电力传输、AMI系统、配网管理等6个方面。其中,一部分差距已经有了清晰的发展方向和解决思路;而另一部分的具体发展方向和解决思路尚不明确。智能电网相关标准的开发需要以具体项目实施为载体,标准体系是否完备需要通过具体项目检验和修订,同时具体项目的顺利实施也有赖于标准体系的约束和规范。针对中国某省级电网的特殊性和典型性,建议其智能电网的发展,一是应重点关注标准研究方向,二是由此引出的示范工程项目。     

Targeting for cogeneration potential through total site integration

Total site integration offers energy conservation opportunities across different individual processes and also to design as well as to optimize the central utility system. In total site integration of the overall process, indirect integration with intermediate fluids or through a central utility system are preferred as it offers greater advantages of flexibility and process control but with reduced energy conservation opportunities. To achieve the maximum possible indirect integration between processes assisted heat transfer, i.e., heat transfer outside the region between process pinch points, plays a significant role. A new concept is proposed in this paper for total site integration by generating a site level grand composite curve (SGCC). Proposed SGCC targets the maximum possible indirect integration as it incorporates assisted heat transfer. In this paper, a methodology is proposed to estimate the cogeneration potential at the total site level, utilizing the concept of multiple utility targeting on the SGCC. The proposed methodology to estimate the cogeneration potential is simple and linear as well as utilizes the rigorous energy balance at each steam header.
