Operating and Planning Electricity Grids with Variable Renewable Generation: Review of Emerging Lessons from Selected Operational Experiences and Desktop Studies (World Bank Studies)

The paper ‘Operating and Planning Electricity Grids with Variable Renewable Generation: Review of Emerging Lessons from Selected Operational Experiences and Desktop Studies’ focuses on analyzing the impacts of variable renewable energy on the operation and planning of the the power system (mostly, generation system). It is aimed at informing stakeholders in power utilities, regulatory bodies and other relevant audiences, on the fundamentals of technical challenges and approaches to operate electricity grids with renewable energy. It covers renewable energy as a whole, but in particular, focusses on wind and solar energy. It also presents three case studies of countries, including China, Gemany and Spain.

The total worldwide installed capacity of wind and solar projects is growing rapidly, and several countries are noticing increased penetrations of wind and solar in their electricity generation mix. In addition to operating experience being gained from adding wind and solar capacity, several grid integration studies have been performed that assess potential grid and operating impacts from adding higher amounts of wind and solar capacity. Perhaps just as important, the electric power industry and those that conduct research on grid integration have not found a maximum level of variable generation that can be reliably incorporated, and it is clear that it is as much an economic question (how much cost in additional reserves or grid impacts is acceptable) as a technical question regarding grid operators ability to adapt to the new challenges.

In addition, while their contributions to capacity or ‘firm’ power and associated costs are different from those of conventional power sources, variable renewable generation technologies can contribute to long-term system adequacy and security. The paper describes on the contribution of variable power sources to long-term supply adequacy requirements, i.e. how much sources like wind and solar power contribute to ‘firm supply’ in a system. It also describes methods to find out to what extent they contribute and at what cost. It also aims at providing indicative answers to how costs to system operations be determined and when and how an integration study be done to estimate the short-term reserve costs of renewable energy.

The concepts in the paper should be of interest, especially to grid planers. For grid operators, the paper summarizes a menu of strategies that the operational practices and desktop research tell about managing wind in a system at different levels of penetration. It also elucidates available strategies, amongst other crucial questions of operational impacts and challenges that operators need to be aware of, to integrate variable generation.

Renewable Electricity Generation: Economic Analysis and Outlook

This volume examines the outlook for renewable energy in electricity generation-particularly wind and solar power-as a substitute for conventional fuels such as coal and natural gas. Economist Benjamin Zycher evaluates the central arguments in favor of policies that would make way for broader use of renewables and concludes that all are deeply problematic. “Renewable” energy sources are not superior in cost to conventional fuels; nor are they less taxing on the environment. The popular argument that increased use of renewables will create “green jobs” is likewise a fallacy-because wind and solar power are costly and inefficient, the net economic impact is a negative one. Zycher concludes that resource-use behaviors emerging from market competition are the best guides to effective, sustainable energy policies.
