It appears that IPOPT is not in your Matlab path or is not correctly installed. Please ensure that IPOPT is installed and working correctly by running the tests for the OptiToolbox or getting help from their forums. MATPOWER will not be able to use IPOPT successfully, unless and until it is installed properly and the output of the 'mpver' command confirms this.
