Study on a Novel Economic Load Dispatch Control of Power Systems in Kyushu Region Taking Massive Installation of Solar Power Generation and Transient Stability into Consideration
Summary
In this paper, we propose a novel economic load dispatch control of power systems including the constraints on the transient stability in the optimal power generation mix in Kyushu region taking massive installation of photovoltaic (PV) system into consideration.
According to the recent studies in this field, the extensive introduction of PV system affects the transient stability of the power system. The share of the PV system in the total power generation in Kyushu is expected to grow faster than that in other regions in Japan. In this study, we first divided Kyushu into 4 areas. Then we evaluated the power system stability of each area by using the network flow model, in which the constraints on the transient stability were taken into consideration. Then we clarified the optimal power generation mix, by minimizing the system’s total cost with linear programming. Our results showed that the constraints on the transient stability affected the optimal power generation mix and caused the suppression of PV outputs.
