What is distribution network expansion planning (DNEP)?

Many studies have been conducted on the distribution network expansion planning (DNEP) problem in recent years. The primary goal of this issue is to satisfy electric load demand, taking into account economic and technical considerations. In the past, this planning was done in a centralized manner with all the information available.

Is the distribution network planning model based on an objective function?

Since the distribution network planning model based on optimization with an objective function was presented in the seventies, until now, almost all research works have been done based on the development of this model. During the last four decades, research studies have been based on the following two approaches:

What are the requirements for connection of distributed generation?

Connection of distributed generation requires network studies to be undertaken, requiring up-to-date digital representations, typically to 11 or 33 kV (MV) distribution.

How can a network shape the future of the distribution grid?

Networks that deploy an agile approach, follow the principles of lean product development, and unlock value quickly have an opportunity to take a leading role in shaping the future of the distribution grid. But only by harnessing the power of data and technology in combination with collaboration can they make this a reality.

How can uncertainty sets be expressed in a distributed network system?

The uncertainty sets can be expressed through binary variables and linear constraints, and the bilinear terms can be transformed for quick resolution. To evaluate the effectiveness of the proposed model and method, we conducted a test using the IEEE 33-node distribution network system .

Why is the distribution network evolving into an active distribution network?

With the expansion of distributed generation in the distribution grid and the development of advanced metering infrastructure (AMI) and information and communication technologies (ICT), the traditional distribution network is evolving into an active distribution network.
