You should be able to open it using Intent. A quick search for the power settings activity has found the setting com.android.settings.widget.SettingsAppWidgetProvider. You should be able to open it from your Activity using the code:

startActivity(new Intent("com.android.settings.widget.SettingsAppWidgetProvider"));
