New Infrastructure

With the gradual implementation of the country’s “new infrastructure” strategy, the market demand for infrastructure in strategic emerging industries such as 5G, data centers and electric vehicle charging has become more intense. The multi-station integration business that carried out by power grid companies can effectively meet market demand, avoid the repeated construction and investment problems of state-owned assets, and reduce the cost of operators, Internet enterprises and other customers of infrastructure construction. Combined with the current market demand and the development trend of emerging industries, this paper puts forward the concept of “5G-source network-load storage” multi-station integration which mainly focusing on digital services and energy services, studies the commercial application scenarios of “5G-source network-load storage” multi-station integration, analyzes its implementation optimization path, and provides a reference for power grid companies to accelerate multi-station integration business.

The Development Trend

In recent years, the concepts and practices of smart cities and “Internet plus” smart energy have mushroomed, greatly promoting the development and application of customer-side energy Internet business and stimulating users’ diversified and personalized demand for interactive services of intelligent power utilization. Intelligent power utilization, as the core of the interactive service system, serves as a bridge between power supply departments and customers. Its construction has a direct impact on the efficiency, economic operation and orderly electricity consumption of power grids. In the context of the increasingly intelligent power grid and complex load structure, this paper analyzed the development trend of energy Internet and adopted SWOT to reveal the strengths, weaknesses, opportunities and challenges of power grid enterprises in developing energy Internet, explore their development ideas on energy Internet businesses, and facilitate their development of energy Internet.

Electric Power Grid

Widespread interest in environmental issues is growing. Many studies have examined the effect of distributed generation (DG) from renewable energy resources on the electric power grid. For example, various studies efficiently connect growing DG to the current electric power grid. Accordingly, the objective of this study is to present an algorithm that determines DG location and capacity. For this purpose, this study combines particle swarm optimization (PSO) and the Volt/Var control (VVC) of DG while regulating the voltage magnitude within the allowable variation (e.g., ±5%). For practical optimization, the PSO algorithm is enhanced by applying load profile data (e.g., 24-h data). The objective function (OF) in the proposed PSO method considers voltage variations, line losses, and economic aspects of deploying large-capacity DG (e.g., installation costs) to transmission networks. The case studies validate the proposed method (i.e., optimal allocation of DG with the capability of VVC with PSO) by applying the proposed OF to the PSO that finds the optimal DG capacity and location in various scenarios (e.g., the IEEE 14- and 30-bus test feeders). This study then uses VVC to compare the voltage profile, loss, and installation cost improved by DG to a grid without DG.

The Development Trend

To study the wake development characteristics of wind farms in complex terrains, two different types of Light Detection and Ranging (LiDAR) were used to conduct the field measurements in a mountain wind farm in Hebei Province, China. Under two different incoming wake conditions, the influence of wind shear, terrain and incoming wind characteristics on the development trend of wake was analyzed. The results showed that the existence of wind shear effect causes asymmetric distribution of wind speed in the wake region. The relief of the terrain behind the turbine indicated a subsidence of the wake centerline, which had a linear relationship with the topography altitudes. The wake recovery rates were calculated, which comprehensively validated the conclusion that the wake recovery rate is determined by both the incoming wind turbulence intensity in the wake and the magnitude of the wind speed.
