Evaluation of reliability impacts and benefits of renewable energy integration in modern power systems

拟议的研究将侧重于概率方法的发展，用于定量评估电力系统中可再生能源利用的全系统经济和环境效益，以及对整体系统性能和可靠性的影响。对可再生能源的广泛支持导致电力系统中大规模风力发电的快速增加，并增加了风力和太阳能作为分布式发电源的应用机会。间歇性发电的显著增长、具有高度波动的严重水平的输电阻塞的增加以及分布式发电的相对增长是现代电力系统中的显著变化。这些变化对系统规划和操作提出了新的挑战，以便提供可靠和有效的电能使用。缓解这些问题的长期方法是将电网逐步过渡到智能电网。这些转变进一步表明需要偏离系统操作和规划的常规实践，并研究和开发新的和合适的技术以提高能量效率，最大化可再生能源利用，并保持整个系统的可接受的短期和长期可靠性。拟议的研究将开发方法，考虑到正在进行的系统结构变化，以量化风能和太阳能应用的好处，并评估与可再生能源相结合的电力系统的运行和规划过程中的系统可靠性。其目的是为电力系统规划者和运营者提供有用的指标和有价值的信息，以便在不断变化的环境中最大限度地利用不同类型的能源。这些研究将为风力涡轮机和光伏阵列制造商提供重要的投入，以开发他们的产品，在考虑系统可靠性和经济限制的情况下最大限度地利用可再生能源。所制定的方法还应有助于能源政策制定者和系统管理者制定和执行适当的可再生能源政策和可靠性标准。

The proposed research will focus on the development of probabilistic methods for quantitative assessment of the system-wide economic and environmental benefits from renewable energy utilization in electric power systems, and the impacts on the overall system performance and reliability. Widespread support for renewable energy has led to rapid increase in large-scale wind power integration in power systems, and opportunities for increased wind and solar power applications as distributed generation sources. Significant growth in intermittent generation, increased transmission congestion with highly fluctuating severity levels, and the relative growth in distributed generation are considerable changes in modern power systems. These changes have created new challenges to system planning and operation in order to provide reliable and efficient use of electrical energy. A long-run approach to mitigate these problems is the gradual transition of the electric networks into smart grids. These transitions further dictate a need to deviate from the conventional practices of system operation and planning, and to research and develop new and suitable techniques to increase energy efficiency, maximize renewable energy utilization and maintain acceptable short and long term reliability of the overall system. The proposed research will develop methodologies, considering the ongoing system structural changes, to quantify the benefits from wind and solar energy applications, and to evaluate the system reliability during the operation and planning of power systems integrated with renewable energy sources. The objective is to provide useful indicators and valuable information to power system planners and operators in order to maximize the benefits from different types of energy sources in the changing environment. The studies will provide important inputs to wind turbine and PV array manufacturers to develop their products to maximize renewable energy utilization considering system reliability and economic constraints. The developed methods should also be useful to energy policy makers and system regulators to develop and implement appropriate renewable energy policies and reliability standards.
