Abstract
In this thesis we have presented different ancillary service markets for frequency and voltage control and analyzed the effect of such markets on the control performance of power systems. First we have created different market structures for balancing (regulation) markets. Since the automatic generation control (AGC) to control frequency is quite standardized, we do not change the control but only the market structures and study their effect on frequency control performance. We have shown that by changing the market structure and incorporating generator ramp rates into the market design, a more desirable control performance can be achieved. Next, we have shown that provision for bilateral load following is viable within the conventional AGC framework. In this arrangement the market has not been changed, rather the control has been modified to accommodate the market. We have shown that the proposed method exhibits faster frequency response than separate third party frequency control. Finally we have looked at the feasibility of VAr markets. For voltage/VAr control, secondary control methods are still evolving and there are few markets in operation. So we have proposed a new control method as well as market structures. In a comparative study for feasibility of generator VArs we have shown that it is difficult to avoid locational advantage (and hence, market power) for certain generators.
