The most high profile of those saw Hamilton collide with McLaren team-mate Jenson Button in Sunday's Canadian Grand Prix, forcing him into the wall and subsequent retirement with a puncture.
Considerable criticism has followed for Hamilton, although he has also received support, including from Formula One supremo Bernie Ecclestone.
Addressing the next situation, Hamilton said: "Those two races were particularly frustrating for me because we showed we had the pace to win both of them, yet I only came away with eight points.
"For me, Valencia will now be a weekend of consolidation after two disappointing results in Monaco and Canada.
"I've always gone well at Valencia, finishing second there in every race, and I really enjoy attacking the track.
"It's a difficult circuit with no let-up, but that won't deter me as I'm really keen to get back on track and get back in the points.
"This race will be our third street circuit in a row, so hopefully it'll give me the chance to reverse the bad luck I've encountered in the previous two."
Hamilton knows he should have done better of late, adding: "We've arguably had the fastest race car in the last three races.
"That's really encouraging because I know that, when it's put to best use, I should be able to finish at the front.
"As always, that will be my goal next weekend."
