“…In particular, ISO/RTOs can undervalue transmission projects by ignoring the possible cost savings associated with generation expansion deferrals that may be enabled by a strategic TEP process. The degree of inefficiency is no doubt proportionate to the amount of transmission investment under consideration; this means that the need for proactive planning is particularly important if a commitment is made to plan large interregional grid expansions or even a national grid, as envisioned by some lowcarbon studies (McCalley et al 2017). Thus, a key question is, How should ISO/RTO TEP consider the reaction from generation expansion and how can transmission and resource additions be considered on a level playing field?…”

The power system is currently undergoing a number of changes, including a rapidly evolving resource mix, growth of distributed energy resources (DERs), more active consumer participation, increased deployment of energy storage and hybrid resources, and more advanced communication and control requirements. These changes in the power system present numerous technical, economic, implementation, and policy challenges and research opportunities for power system operators. To help address these challenges, a collaboration among five research institutions-Argonne National Laboratory,

“…The grid planning literature takes a broader market context to evaluate siting and planning decisions, considering a variety of electric system technologies [42,43]. Most of these studies use capacity-expansion methods and focus on the important role of transmission and balancing authorities to manage the variability of VRE technologies [44,45]. Generally, these studies show that a portfolio of resources including VRE, storage, and transmission is needed to transition to a low-carbon energy system [46,47].…”

“…Transmitting variable renewable energy (VRE) to distant load centers through tie-lines is a popular approach to integrate a large amount of renewable energy. 1 For example, several ultra-high-voltage DC tie-lines are constructed to transfer the energy from VRE-rich western China to eastern and southern China as load centers. In this paper, we focus on the scheduling of tie-lines that connect VRE-rich areas (as the feed-out system) and load-intensive areas (as the feed-in system).…”

A promising way to promote variable renewable energy (VRE) integration is to enable more power transmission through tie-lines between distant areas. Practically, because of the dispatching independence of regions, tie-line flows need to be carefully scheduled. The daily energy transmitted follows the daily mean load with a limited variation. Moreover, within a day, the tie-line flow's variation range, its ramping rate, and the number of changes in flows should be limited. Thus, current tie-line scheduling fixes transmission power to relatively constant levels, failing to fit VRE variations and further restricting VRE accommodations. This paper proposes a two-step tie-line scheduling method to promote VRE accommodations by considering VRE variations and above practical constraints, while also considering the cost of the system for providing flexibility. Regarding VRE's daily variability, the annual energy transmission plan between regions is decomposed into daily plans based on both VRE generation and load. For VRE's intraday variability, a dispatch model determining tie-line flows is built with constraints on tie-line flow's variation range, ramping rate, and change numbers. In addition, the regulation costs involving generator deep peak shaving cost and generator ramping cost are modeled with binary variables and included. Numerical studies for Chinese provincial systems show that the regulation costs account for 9% of the total cost and the VRE consumption increases by 8.6% while the cost reduces by 9.5%.
