Abstract
The access of a large number of distributed generations(DGs)will result in complicated power flows in dis?tribution network.To reduce the effect of the access of DGs on the voltage of distribution network and further make full use of the residual capacity of distributed equipment,a control strategy of local reactive power in DGs is proposed based on self-adaptive sensitivity,under which each node obtains its own reactive power-voltage sensitivity by the control and computing capability of inverters,and the Q(U)control curve is configured according to the obtained sensitivity,which makes every node participate in the reactive power control in a more balanced way and thus improves the system's reac?tive power regulation capability.The proposed strategy is simulated and verified on an IEEE 33-bus distribution net?work test system,and results show that when the nodal voltage off-limits occur,the voltage regulation capability and total reactive power compensation capability of the test system are better under the proposed strategy than those under the tra?ditional Q(U)control strategy.关键词
