“…In recent years, with the establishment of the 'Organization for Cross‐regional Coordination of Transmission Operators' of Japan (OCCTO) and the liberalization of the electricity market in Japan, cross‐regional interconnection lines are increasingly becoming important. Wide‐area supply and demand control methods have been investigated to adjust the supply and demand balance by power exchange from areas with surplus reserve capacity to areas with insufficient reserve capacity using cross‐regional interconnection lines. In this paper, we quantitatively evaluate the margin of SR 10 ( SR 10_ margin ) obtained by subtracting the 10‐min residual load fluctuation from SR 10 for the local area when wide‐area supply and demand control is put into practice.…”

As a countermeasure for supply and demand imbalance in case of high penetration of photovoltaic systems, wide‐area supply and demand control is considered. This is performed by adjusting the supply and demand balance by power exchange from areas with surplus reserve capacity to areas with insufficient reserve capacity using cross‐regional interconnection lines. By using our supply and demand control model considering the adjustable range that can respond to a fluctuation after 10 min (10‐min spinning reserve, SR10), we quantitatively evaluate the margin of SR10 (SR10_margin) by subtracting the 10‐min residual load fluctuation from SR10 in the local area. By calculating SR10_margin for each time period (month and time of day) and for different targets for reserve capacity (reserve margin and SR10), we investigate the possibility of wide‐area supply and demand control. We find that SR10_margin can be secured by changing the reserve capacity within the local area, which demonstrates the feasibility of wide‐area supply and demand control in terms of supply and demand balance. © 2020 Institute of Electrical Engineers of Japan.

“…As such, this type of operation is expected to contribute to RES output fluctuation compensation efforts. [8][9][10][11][12] However, in multiarea system operation, there is a possibility that the system power flow state will change in a complex manner due to the RES output fluctuations. As such, in order to stably supply power, it is considered important to determine the dispatch output values of the generators compensating for an RES fluctuation while evaluating the influence of the dispatch output values on the system from various perspectives.…”

Recently, a multiarea system operation utilized a tie‐line has been verified to resolve a shortage of a control capacity of frequency control generators output due to a widespread penetration of renewable energy systems (RES). In order to determine the proper dispatch of the generators output to compensate RES fluctuation in the multiarea system operation, the power system operators should consider power flow constrains and indexes of power system conditions such as the speed of dispatch, the balance of reserved control capacity in each area, and the stability of power supply. In this paper, we propose a methodology to determine multiobjective dispatch candidates of frequency control generators output to compensate RES fluctuation in multiarea system operation considering three indexes, a speed of dispatch, a reserved control capacity, and a transient stability based on optimal power flow and multiobjective particle swarm optimization. The methods determine the dispatch based on Euclidean norm of the indexes in the calculated candidates in order to consider all indexes well‐balanced. The effectiveness of the proposed methodology is verified by a numerical simulation used IEEJ EAST 30‐Machine Grid Model with much RES, and the effectiveness of the dispatch minimized Euclidean norm is confirmed by comparison to single‐objective solution in each index among the calculated candidates.

For a microgrid with a mix of distributed energy resources (DERs), major challenges on its survivability are found in the islanded condition. In particular, a sudden loss of generation or a large and fluctuating load could force the microgrid to operate near its capacity limits. Such a situation can cause a cascading collapse of the system, even when the load demand is within the DER's kW rating -as observed during several tests at the Consortium for Electric Reliability Technology Solutions (CERTS) Microgrid Test Bed. This paper analyzes the prime-mover stalling phenomena behind the system collapse. It highlights how the reserve margin of the system is lowered during transient conditions. Furthermore, two control methods are evaluated to resolve the microgrid collapse problem.
