Electricity grid data analytics as a moduled service for production, delivery, and distribution of power as a dynamic demand response within a renewable energy-based electricity grid infrastructure

Abstract

A renewable energy-based electricity grid infrastructure utilizes distributed data analytics to enable modeling and delivery of an appropriate, time-sensitive, dynamic demand response from multiple renewable energy components to an intelligent power distribution network. Data processing resources are identified and aggregated within a distributed computing infrastructure to provide dynamic demand response as a service of a dedicated grid data analytics module. Aggregation of processing resources for grid data analytics also enables the electricity grid infrastructure to virtually, optimally and adaptively make decisions about power production, distribution, and consumption so that a demand response is a moduled service of the electricity grid infrastructure, and enables distributed energy generation from multiple renewable energy resources that is responsive to various types of grid demand situations, such as customer demand, direct current-specific demand, and security issues, and so that power production is substantially balanced with power consumption.

Problems solved by technology

Despite technological advances in developing renewable energy resources and in electricity grids, current energy infrastructure suffers from many limitations that need rapid improvement as demand for such power increases, and grid security importance and regulatory requirements for use of “green” resources become more prominent.

Power derived from renewable energy such as solar, wind, wave, and solar thermal resources are becoming increasingly relied upon, but each includes several limitations that impede them from becoming widespread, low-cost, efficient, and continually viable sources of electricity.

Each is inherently unreliable, owing to factors such as changes in the time of day and variations in weather conditions that mean that maximized performance of components for each resource is very difficult to manage.

Combining any of these together proves even more difficult to manage the inherent inefficiencies involved in operating devices and components to meet energy demand.

Offshore energy installations present many complicated challenges.

However, implementing offshore installations are extremely challenging, time-consuming, expensive, and environmentally sensitive.

Just a few examples of issues that present significant challenges include storage of power, its transmission to the onshore power grid, providing power to the offshore installation itself, maintenance, distance from the electricity grid, and exposure to weather elements.

Additionally, building a large-scale multi-resource platform or installation is very expensive and often has a large environmental impact footprint, making such an installation a questionable investment.

All of these issues can reduce the attractiveness of constructing and operating such an installation.

Storage issues are a particularly challenging problem attendant to transferring power generated offshore to the onshore electricity grid.

The electricity grid itself contains limited inherent facility for storing electrical energy.

Power must be generated constantly to meet uncertain demand, which often results in over-generation (and hence wasted energy) and sometimes results in under-generation (and hence power failures).

Additionally, there is limited facility for storing electrical energy at the point of generation, particularly in the case of offshore installations where available space must be maximized and cost and environmental issues are major considerations.

For example, there are inherent market biases favoring the use of existing, non-renewable energy resources.

Existing energy production infrastructure strongly favors the use of non-renewable energy resources, and the costs of generating power from renewable energy resources are far higher, despite the availability of and ease with which wind, solar, wave, and solar thermal energy can be obtained.

Additionally, energy commodity prices and weather conditions fluctuate widely, making it very difficult and often prohibitively expensive to efficiently generate, transmit, and distribute power derived from renewable energy resources.

These fluctuations, and the inherent inefficiencies resulting from them in utilizing renewable resources, make it difficult for providers to justify investing in the infrastructure needed to develop, transmit, and distribute power from renewable energy resources.
