  • Variable Energy Sources: How to Integrate Renewables into the System [From the Editor]
    System planners and operators routinely deal with the challenges of the large-scale integration of wind and photovoltaic resources. Even New England has well over 2,100 MW of photovoltaic resources and 1,300 MW of wind generation in a system that peaked this past summer at approximately 23,800 MW. The region boasts the first offshore wind farm in the Western Hemisphere and has approximately 5,400 MW of wind generation in the interconnection queue. The growth of clean renewable sources has given rise to duck curves in the region. Given the lower costs for renewables and government programs, growth forecasts for inverter-based resources remain high. The anticipated system changes challenge our traditional thinking about the electric power system and the rules of thumb used to plan and operate the network. Weak grids with up to 100% asynchronous generation are a now a reality on some systems.

    Discusses the importance of becoming a PES society member and volunteer.

  • A Major Player: Renewables Are Now Mainstream [Guest Editorial]
    The Utility Variable-Generation Integration Group (UVIG) has focused on the integration of wind, and more recently solar, power into electric power systems. The industry focus is now concentrating around how to integrate inverter-based power plants into weak grids and, indeed, how to design a grid for 100% nonsynchronous generation. The focus is no longer on how to integrate those alien forms of generation from Mars into the grid but how to integrate the energy systems of the future, of which renewable energy systems are a major part, into a coherent whole. Examines how this will likely develop over the coming years.

  • It's Indisputable: Five Facts About Planning and Operating Modern Power Systems
    An indisputable fact cannot be rebutted. It is supported by theory and experience. Over the past 25 years, wind and solar generation has undergone dramatic growth, resulting in a variety of experiences that model the integration of wind and solar into the planning and operation of modern electric power systems. In this article, we bring together examples from Europe, North America, and Australia to identify five indisputable facts about planning and operating modern power systems. Taken together, we hope these experiences can help build consensus among the engineering and public policy communities about the current state of wind and solar integration and also facilitate conversations about evolving future challenges.

  • Maintaining Balance: The Increasing Role of Energy Storage for Renewable Integration
    For nearly a century, global power systems have focused on three key functions: generating, transmitting, and distributing electricity as a real-time commodity. Physics requires that electricity generation always be in real-time balance with load-despite variability in load on time scales ranging from subsecond disturbances to multiyear trends. With the increasing role of variable generation from wind and solar, the retirement of fossil-fuel-based generation, and a changing consumer demand profile, grid operators are using new methods to maintain this balance.

  • Uncertainty Forecasting in a Nutshell: Prediction Models Designed to Prevent Significant Errors
    It is in the nature of chaotic atmospheric processes that weather forecasts will never be perfectly accurate. This natural fact poses challenges not only for private life, public safety, and traffic but also for electrical power systems with high shares of weather-dependent wind and solar power production. To facilitate a secure and economic grid and market integration of renewable energy sources (RES), grid operators and electricity traders must know how much power RES within their systems will produce over the next hours and days. This is why RES forecast models have grown over the past decade to become indispensable tools for many stakeholders in the energy economy. Driven by increased grid stability requirements and market forces, forecast systems have become tailored to the end user's application and already perform reliably over long periods. Apart from a residually moderate forecast error, there are single extreme-error events that greatly affect grid operators.

  • The Power of Small: The Effects of Distributed Energy Resources on System Reliability
    It's a sunny day in Honolulu, Hawaii , and rooftop photovoltaic (PV) systems across the island are serving a significant penetration of the load. A large generator trips offline, and frequency drops quickly-to the point where a block of load is shed to restore the balance between generation and load. However, disengaging those feeders disconnects not only the load but also the PV generation on those feeders; so balance is not restored and frequency continues to drop.

  • Paving the Way: A Future Without Inertia Is Closer Than You Think
    Unless you have been hibernating in a remote cave for the past decade, you will have noticed the explosion of variable renewable generation. Wind power and solar photovoltaics (PVs) have been the subject of dozens of articles, just within the pages of IEEE Power & Energy Magazine. Charts illustrating relentless growth, such as the example from the United States shown in Figure 1 with futures tending toward 100% renewable energy, are common. This figure, provided by the National Renewable Energy Laboratory (NREL), reflects a low-cost, high-renewable projection scenario.

  • Electricity Markets and Renewables: A Survey of Potential Design Changes and Their Consequences
    The design of wholesale electricity markets is complex. Unlike other commodities, electricity cannot be stored in a warehouse. Electricity generation must occur simultaneously with consumption, whereby electricity delivery is based on laws of physics. Under the structure of regulated electricity rates, consumers are generally not directly exposed to the instantaneous cost of the delivered electricity. Countries around the world have successfully managed these complexities by restructuring the electricity sector with markets that allow wholesale electricity suppliers to compete in providing energy, reliability services, financial services, and sometimes capacity. Still, wholesale electricity market restructuring has certainly been a moving target.

  • Wide-Area Planning of Electric Infrastructure: Assessing Investment Options for Low-Carbon Futures
    Electric infrastructure worldwide has evolved significantly over the last decade, as nations increase the renewable share of their generation portfolio and build transmission to move energy from the resources to the load centers. Since 2007, the United States has increased its percentage of electric energy generated from wind and solar from lower than 1% to 7.5%, Europe from approximately 3% to over 13%, and China from 1% to 5%.

  • Operating Waterside: Interesting Facts About How It Was Done [History]
    Waterside was an iconic generating station built by the New York Edison Company and later operated by the Consolidated Edison Company of New York. It served as a primary source of electric power for Manhattan island throughout the 20th century. The following is not an exhaustive technical history of the station but, rather, a collection of interesting facts regarding procedures involved in operating this huge facility over the decades of its existence.
